I don't understand all the comments on Soarin. It's a must-do for us, usually more than once each trip if we can. To me, it really makes you feel like you are flying, which is an awesome feeling.
I've also never understood the lack of love for DHS. I agree that it doesn't have as much as some of the other parks, but it's got two of the best Disney attractions (ToT and RnR) and we really enjoy all the shows.
Overhyped:
Toy Story - it was a fun ride and I understand that a lot of it's popularity is due to it being one of the few family rides at DHS, but it just wasn't nearly as awesome as I expected. There are very few rides I'd wait longer than 20 minutes for and Toy Story isn't one of them.
Test Track - Probably one of the most boring rides I've been on. The first time we went, we got off thinking "is that it?" We do still ride it, because the younger kids like it, but we would never wait in a long line for it.
Space Mountain - It looks very cheap and dated and it's incredibly rough, always giving me a headache. This makes me sad because I have fond memories of riding Space Mountain in
Disneyland back in the 80's and 90's. But I just don't like riding the WDW version now.
Must Do's - Splash, Pirates, Haunted Mansion, Rock N Roller, Tower, Soarin, Everest, Safari, Lion King
