All of the buildings are the same as far as the style of rooms. We stayed in the Dalmation building near the front of the resort and it was quiet. We took a walk through the buildings one night on our way home and kids were playing handball against the walls--on the inner side near the pool. Lots of kids jumping off of the balconies (for fun--whatever that means). If you've ever stayed at an EconoLodge, the rooms are setup exactly the same.
It's all in what you want as far as decor goes---and a request does not guarantee that's where you will be put. I requested the Buzz and Woody building because my son LOVES them and got put into the Dalmation building for 8 nights. Big disappointment for him, but I wasn't unpacking 9 days worth of clothes for 3 of us to move after a couple of days. I just don't understand why they can't put you in the building you request if it's on your reservation.
So beware of that---what you want is what you might not get anyhow. Have fun!
