You can use either pool (except for this upcoming January when the Jambo pool will be closed for refurbishment) but it is a far walk between the two (about 1/2 mile), although you can take bus between the buildings (park busses stop first at Kidani and then go to Jambo, DD bus stops first at Jambo and then goes to Kidani). There are bathrooms. Personally, I would likely not do the trip with very young kids in tow but many probably will try it.
