Both resorts have lovely pools. I know that you have already received info regarding pool depths, slide info and the use of flotation devices.
Not sure what you mean by moving around the area? Do you mean bus transportation from the resorts, bus transportation within the resorts, or walking distances between various parts of the resorts?
The best way to determine which resort is best suited to your family is to look at each of the resort specific threads. There are lots of photos as well as detailed descriptions there. Those are also the places to post questions that are specific to each resort.
Good luck with your quest. I'm sure you'll enjoy whichever resort you select. I could give you my pick of the 2 resorts, but since my preferences may not be anywhere close to yours, it really isn't helpful IMO.
