MK: Don't Miss:
Splash mountain---the first time I went on it I was awed at how much of a ride it really was.
Railroad---a nice trip encircling the whole park.
Haunted Mansion
Pooh---especially if you are a pooh fan, very cute!
People Mover (Tomorrowland Transit)---its neat to circle around Tomorrowland and go in and out of the Tomorrowland attractions!
It's a Small World---the ultimate classic and awesome (contrary to other people's beliefs)
Pirates of the Caribbean---see above
Skip:
Mickey's Toontown Fair---unless you have children, wall to wall people can be skipped!
Magical Moments Parade---how old is this parade now?
Tomorrowland Speedway---again unless you have children aged 5-10.
MGM Studios: Don't Miss:
RnR
ToT
Great Movie Ride---who knows how much longer this will still be the same (there at all in any of its current existance?)
Muppet Vision 3D
Indiana Jones Stunt Spectacular---unless already seen before (this attraction need an overhaul with action sequences from the other movies)
Skip:
Sounds Dangerous---more like sounds snoring ZZZZ!
Voyage of the Little Mermaid
EPCOT: Don't Miss
WS---all the countries are worthwhile---Interact with the cast members of each country, it will make it so much more interesting!
Spaceship Earth---one of the few originals left from FW that had that awe inspiring ride experience like Horizons and World of Motion and the old JIYI used to have
Test Track
The Land
The Living Seas
Tapestry of Nations---awesome music!
Illuminations
Skip:
Wonders of Life
JIYI
Honey I shrunk the Audience
Innoventions---unless you just want to see big corporate stands promoting their corporation in the most boring way---what ever happened to Communicore?
Animal Kingdom: Don't Miss:
Tree of Life/Tough to be a Bug---save for later in the day (less crowded)
Dinosaur---very scary for young children, otherwise it is a blast!
Kilimanjaro Safaris---go as early in the morning as you can (otherwise the animals duck for cover in the hot afternoon sun---just like real life though)
Kali River Rapids
Maharajah Jungle Trek---especially if you like Tigers
Tarzan Rocks
Skip:
Camp Minnie-Mickey
Pangani Forest Exploration---ZZZZZ!
Conservation Station---other than the train ride there---see above.
Remember to go at your own pace and take in the whole atmosphere of each park---which is probably the greatest attraction of all, well next to the smiles on everyones face!
