Hi,
To get 3 actual beds you would want
Grand vista dedicated 2 bedroom (not lock off) or a 3 bedroom
Harbour lake dedicated 2 bedroom (not lock off)
Lakeshore reserve dedicated 2 bedroom or any 3 bedroom
Imperial Palms-- only 3 bedrooms
Sabal palms
Harbour lake is more for families with little children but my husband and I enjoyed it last year. 2nd bedroom has view of the corridor.
Grand vista has some really nice evening adult activities and the second (and some 3rd) bedroom has same view as master.
Lakeshore is fantastic -my only complaint is that the balconies are not screened. Master and 2nd bedroom have the same view.
Sabal Palms is very close to disney. It is on the Marriott World Centre campus (and very close) so you have access to the pools, restaurants, and health club there.
Almost all of the 2nd bedrooms look out over the entrance way.
There are a couple of stairs in the unit in two locations. two stories and no elevators.
Imperial palms has 3 bedrooms and two bathroom. 1King, 1 queen and sofa, 2 single beds. It is the closest to Disney. You have access to the Marriott World centre. A bit farther from the World Centre pools but they have a shuttle.
All of these will provide you a great vacation.
