If you want zero entry pool, there is one outside of building 5 with the lazy river. Building 4 is right next door and has a pool that is your basic old fashioned pool. Building 6 on the other side has a zero entry pool as well, but not sure of the views on this one. My suggestion, building 4 or 5 if you want the fireworks views and request high up as possible....
That being said so many pools around you can't go wrong there...I Loved the pool by the check in building which also has a lazy river, zero entry and kids splash area. And its a short walk from building 4 or 5. This pool seemed to me to be less crowded.
We didn't get the view I wanted with our last trip, first time it happened to us in 3 trips, and we still had a great time.
