I'll take a shot in the dark with this.
I'd say as long as you can provide your own transportation back to the ship you can stay as long as you like.
This makes sense to me especially with the cost to go there in the first place.
Another factor would be the operational hours.
Most excursions will give you a time to be back at a meeting place to get the transportation back to the ship.
It's not like they tether you together, LOL
WOW finding out the pool hours was not easy but you got me curious on this.
It looks like the pools and waterslides are open 10-6pm. But there are so many things offered there I suppose you could find activities to get into.
