As to choosing among Poly, BWV, and AKV, be aware: (a) Poly has the largest studios, had a refurbishment in 2021-22 and thus rooms are in excellent shape, and there is the queen bed, a pull down from the wall Murphy bed for 2, and another smaller Murphy bed (fine for either of the kids), that pulls out of a cabinet beneath the TV, and the two showers.
BWV is undergoing refurb now and should be done by March 2024, meaning you likely will get a room that is practically new if you reserve there. It will also have the Murphy pull down from the wall and the smaller Murphy pull out from a cabinet.
AKV will have a room refurbishment going on in 2024 and thus will likely be occurring in March 2024. Probability is that you would not get a room that has completed the refurb, but instead one that has not had a refurb in 7 years, which still has the pull-out couch bed which are not as comfortable as the Murphy pull-downs from the wall. Also, AKV studios do not have the Murphy bed that pulls out of the cabinet. Also, if desire is to be near the pool, a non-guaranteed room location request for near the pool should be made, because at Jambo, your room can be near to very far form the pool, and if Kidani, the room can be extremely far (more than 1/3 mile from the pool.
