They don't really compare at all, but we actually prefer the BWI pool to SAB. SAB is really spread out so there is no place you can actually swim. At BWI, DH and DS9 can do swimming races together and have some space. We also like it because the slide is super fun (yes, it's a clown) and you can see the kids the whole time they are walking up to the slide and waiting for the slide. You don't have to leave the pool area and cross a pathway to get to the slide. The pool bar is also right inside the pool area, so you don't have to leave the pool or take your eyes off your child in order to get a drink or snack. They also have really cute pool parties.
