Does it have a lazy river

Yes in the water park.

Yes and its very packed mid-day. Still very nice.

Yes it has a fabulous Water Park area.

Yes, and it has a current throughout the whole river so you don't have to worry about pushing yourself to move. There are fake trees on a platform in the middle of the lazy river that have fake coconuts, that work as buckets. Water fills them up, then when they are full enough, the water can dump on you if you are close enough.

Yes
