I'm in building 1. It's the first building built.
Pros: next to main pool, recreation/check-in building, deli, and bar
Haven't had any problem finding parking, even when returning late. Even if the closest parking was filled, there is plenty of parking available nearby next to the check-in building.
Close to resort exit (don't have to drive thru entire resort to exit)
Cons: none really. Even though it's the oldest building, it isn't all that old (maybe 4 to 5 years), and is in great shape. When they have a pool event (dive-in movie, some kind of entertainment), you can hear it in the room a little. But it's not bothersome, and is always over by 9 or 10 pm.
My preference, no matter what building you get, would be for rooms ending in 05 thru 11, and on floor 2 or higher.
btw: now that building 7 is open, they've opened the road all the way around the resort (it only went part way around while construction was going on, so building 5 and 6 had to go thru the entire resort to get to their building). Now buildings 5-7 can go directly to their buildings without going all the way around.
