Our paths must have crossed at some point in the last couple of days. I just got home from 2 days at WDW, 3 days at USF/IoA, and a day at SW.
Sounds like a nice trip -- I was only there for a few days, staying with family. Have a Uni AP and lucked into the SW tickets. I wrote some comments on the SeaWorld section of the board, but since no one checks there, I'll chime in here.
I saw all of the SW Christmas shows except for the Sesame Street one, and found all to be of high quality -- especially considering that the holiday offerings are not part of an upcharge event. The Sea of Trees was beautiful, and the fireworks/fountains finale was more moving and inspirational than Uni's Cinematic Spectacular, which wasn't bad, but did come off as one long commercial that didn't integrate the water screens well with the lasers and fountains.
We only got around to seeing four of the shows, but I agree with you -- the Sea of Trees was the big surprise for me. I thought they integrated the trees and fountains very well into the fireworks show, too. Clyde and Seymour's Christmas Show was great. The mime who does the preshow is a wonderful entertainer. I remember seeing him a couple years ago and thinking the same thing. And the Winter Wonderland ice-skating show was probably the highlight for me. Just a very unique offering for a theme park.
SW's seasonal food offerings are great as well... the s'mores "cobbler" was delicious. Not only does SW have special napkins, but also special bags with the "Seasons Meets the Seas" logo. Moreover, the cups for hot chocolate in the Arctic section are specifically tied to the Polar Express overlay (which itself was a lot of fun, and much more than the simple film swap that I was expecting), and have a special "P.E." logo. As far as I could tell, only the cups at that particular location were themed as such... I can't imagine WDW having cups or napkins that are not only seasonal, but tied to a single locale or attraction.
Had the s'mores cobbler, too. A good snack to share. Also liked the Polar Express and was surprised by how much effort they put into it. The doors in the loading area are made to look like a train, and overhead they've hung branches to give the area a forested feel.
SW got progressively busier starting in the mid-afternoon, and by evening it was packed. It wouldn't surprise me if the event has been increasingly popular with locals -- there really is a pervasive holiday feel and atmosphere there that you just don't get at the other Orlando parks.
Wouldn't surprise me, either. My family agreed we would go to SW if we were looking for a Christmas experience. Candlelight at Epcot is a great show, but it's such a hassle with the show always filling up and the park has such few offerings otherwise, that it's not something I'd want to do every year.
I can't stress enough how decorated the park is. There are garland, ornaments, lights everywhere. It feels like everything that can be decorated, is. There's a sign near the photo shop at the entrance with a bunch of penguins. They were decorated with Santa hats and scarves. The counter-service place we had dinner had a Christmas tree inside, garland around the room, and decorations around the ordering area. And Christmas music playing.
I thought Universal's holiday offerings were pretty good too, though. I was impressed that an hour-long performance by Mannheim Steamroller was part of the Studios admission; I was expecting a 15-minute truncated "best of" concert, and was pleasantly surprised that they went all-out. The Grinchmas show at IoA also had high production values, but on the whole IoA seemed to have fewer holiday offerings than its sister park. (And Mythos is an amazing value as a sit-down theme park restaurant, even if its decor looks like it came out of a bad '70s B-movie fantasy.)
I was disappointed with IoA's decorations, which are almost entirely relegated to Seuss. Now, Seuss Landing looks excellent, but seems like there's so much potential in the other Islands, that it feels like a missed opportunity. I thought the Grinchmas show was fine -- high production values, yes. But I'm also not a fan of the Jim Carrey Grinch movie, so that probably factored into my feelings. And the Whoville people just look strange. The actors were definitely engaging, but there's just something about those noses. I thought Clyde and Seymour at SW was far more entertaining.
But the Studios park had decent decorations around the New York section, and the big Macy's-like balloons scattered around the park. Christmas music playing there, too. I liked the parade -- the man standing next to me seemed to really like the candy-cane girls.
Who could blame him?
Not related to Christmas offerings, but Turtle Trek at SW was a lot of fun. Cool to see new technology/experience in Orlando. Trek had a distinctive EPCOT/Living Seas vibe, even down to the background music in the queue. The Sky Tower is now included with park admission, not sure when that change was made. Enjoyed going up and looking for the Uni and Disney landmarks on the horizon.
And Manta -- such a fun ride. Very interested to see how Antarctica turns out. Judging by the construction walls, it has a huge footprint in the park.
