MK - Snow Whites Scary Adventures. I never understood why the waits were so much lower here than at Pooh. Same type of ride (dark), similar theming, but if pooh was 60 minutes, Snow was 15 tops. Load speed seems the same, ride systems similar, but not near as popular. "I prefer snow over pooh."
I LOVE the Snow White ride as well and will be devestated to see it go. As to why the waits are shorter, perhaps one factor is that it has 3 rows per ride vehicle as compared to the 2 in Pooh (and 1 in Pan). Also, it doesn't use Fastpass, so the makes the standby wait at SW faster than the others.
As to what is underrated at the parks, my answer is
EVERYTHING that isn't a big flashy highly touted high-tech "E-ticket", most of which are Disney's take on thrill rides. There are so many great experiences to be had in each park that so many people miss out on in the race to do "the major attractions". Including but not limited to:
Magic Kingdom
Main Street Vehicles - Yes, they are on a limited schedule now, but they still run, with the Horse Cars running every morning except when the track is being worked on. (in which case the Omnibus, Fire Engine, or Jitney will be out instead)
WDW Railroad - classic and iconic tour around the park!
Swiss Family Treehouse - very creative and well-done walk-through that stimulates the imagination of what it would be like to live in a tree!
Country Bear Jamboree and Enchanted Tiki Room (hopefully to soon feature a return of the original show) - the animatronic musical reviews are cute, fun, and funny, and feature a lot of catchy singalong songs. Among my favorite things in all of WDW.
Tom Sawyer Island and Liberty Belle Riverboat - fun island to explore and take a scenic ride around
It's A Small World - my favorite attraction in all of WDW and my favorite of all the "E-tickets", but it doesn't seem to get the fanboy love that the other E-tickets do. And sadly, its catchy and addictive theme song and inspiring message of tolerance and peace is often mocked by the more cynical and jaded set.
Snow White's Adventures, Pooh, and Peter Pan - these are short but VERY sweet and VERY charming, and perfectly tell the story of their respective films in their 2-4 minute format. They get a lot of riders but not a lot of fanboy respect, but I prefer them over most "E-tickets" (including the highly touted Pirates and Mansion) ANY DAY.
Dumbo, Teacups, and Carousel - these charming attractions get a lot of riders, but not a lot of fanboy respect.
Mickey's Philharmagic - my favorite 3D attraction I've ever experienced and IMO one of the best attractions in all of WDW. Very cute, charming, and funny; it features extremely catchy music and is highly repeatable
Mickey's Toontown Fair, especially Mickey and Minnie's House - This late, great, section gave guest the chance to visit the whimsical cartoon world where the "Fab 5" lived and explore their homes. Again, not everything has to be an E-ticket (or even a ride) to be worthwhile. Walk-throughs are worthwhile, too, and have a precedent in the parks dating back to Tom Sawyer Island and the Treehouse.
Carousel of Progress - a classic Walt Disney Animatronic show. It has a very warm vibe (especially in the last scene) that I really like.
Peoplemover - This seems popular with the fanboys, but a lot of "mainstream" guests probably miss out on this scenic and relaxing ride.
Speedway - I don't get the fanboy hate for this attraction
Stitch's Great Escape - I don't get the fanboy hate for this one either. It's my favorite of the 3 attractions that I've experienced in that location
Epcot
Journey Into Imagination with Figment - OK, so it's not as good as the first, but it's still arguably the cutest, happiest, and most whimsical attraction in all of Epcot!
Captain EO/HISTA - both are much better than fanboys make them out to be! They are both extremely well done and enjoyable, IMO.
The Seas With Nemo and Friends - The Nemo dark ride (one of my favorites at WDW and second fave attraction at Epcot) has revitalized the pavillion without taking away the ability to view the tanks in the postride area. You can still watch the fish feed, dolphin presentations, manatees, etc. This whole pavillion is criminally underrated.
Living With the Land and Circle of Life - there is much more to this pavilion than Soarin!
Universe of Energy - another underrated attraction with awesome dinosaur scenes. I prefer the Ellen version over the original because the rest of the attraction is now more humorous and entertaining, IMO.
Gran Fiesta Tour - El Rio was one of my favorite attractions in Epcot and all of WDW, and this new version tops it in both the whimsy, cuteness, and happiness scale, IMO. Very colorful, festive, funny, fun, and repeatable.
Maelstrom - a short but sweet classic Disney dark ride
World Showcase Films - France, China, Canada, and Norway films give a nice travelogue tour of their respective countries and enhance the World Showcase experience. The Norway film is shorter than the others but is better than the fanboys make it out to be.
World Showcase Art Galleries - offers educational and interesting displays that enhance one's enjoyment and appreciation of their respective countries and pavillions.
World Showcase Performers - great musical (and other) groups that enhance one's enjoyment and appreciation of their respective countries and pavillions. My favorites include Mariachi Cobre, British Invasion, Octoberfest Musicanten, and the sadly removed due to budget cuts Dragon Legend Acrobats, Si Xian, and Spellman's Gledje.
Animal Kingdom
The whole park - Yes, the whole park is criminally underated!
It's Tough to Be a Bug - rivals Mickey's Philharmagic for best/favorite 3D park attraction I've ever seen. Very cute, charming, funny, and repeatable!
Tree Of Life - My favorite of the 4 park icons, this is truly an inspiring work of Art and IMO, finding the animals carved into the Tree is an "attraction" in it's own right!
Affection Section/Rafiki's Planet Watch - I don't care how many "regular zoos" have contact yards - the ability to experience one and meet animals is always a highlight of my day whenever I can do it!
Maharajah Jungle Trek, Pangani Forest, Oasis, and Discovery Island Trails - Among the most well-themed animal trails found anywhere, I can easily spend at least 30-45 minutes per day on each of these, enjoying both the animals and the atmosphere!
Flights Of Wonder - Easily the best live bird show I've ever seen, and it strikes a nice balance between amazingly talented birds (such as Groucho, who can sing 7 different songs) and the hilarious antics of Guano Joe, the tour guide who lost his tour group and has "FOB"!
Pocahontas and Her Forest Friends - this sadly defunct show featured lots of cute and charming animal behaviors, combined with a touching and powerful message and one of the most beautiful Disney songs ever written, "Colors of the Wind". It was certainly better than the empty theatre that sits there now!
Hollywood Studios
Walt Disney: One Man's Dream - this is nirvana from Heaven for a die-hard Disney - and WALT Disney - fan! Not only is the movie great and very touching but I could EASILY spend at least an hour per day looking at and reading all of the exhibits and signs in the galleries that proceed the film - and often do!
Magic of Disney Animation - Nirvana from Heaven for a die-hard Disney animation fan. I absolutely LOVE looking at the concept art, maquettes, etc., of each new Disney and Pixar animated feature. Also, the initial presentation featuring Mushu is HYSTERICALLY funny and I enjoy attempting to learn how to draw the characters in the Animation Academy.
Beauty and the Beast: Live on Stage - Catchy songs, a great story, and an INCREDIBLY moving finale make this a must-do heavy repeater for me!
Voyage Of the Little Mermaid - another Studio favorite that, like BatB, perfectly condenses the story of the Animated Classic into the theme park format. The uber-catchy "Under the Sea" number featuring all the cute animal puppets is my favorite part of the show and makes it highly repeatable for me!
Playhouse Disney: Live On Stage - another underated show that most "adults" probably overlook because it's targeted at children. But the songs are catchy and the puppets are very cute. And any show featuring Mickey and the "Fab 5" gang gets points in my book!
Sounds Dangerous - I don't get the fanboy hate for this. The "binaural sound" is extremely convincing and impressive, not just in the main show, but also in the postshow booths.
