Stayed in Residence Inn last June and had a suite with 2 doubles and also sleeper sofa in living room.
Another option if there are 6 of you is Floridays resort practically next door. Smallest unit is a 2 bed condo. Room 1 has super king bed with ensuite and jacuzzi bath, room 2 has 2 double beds and a full bathroom beside it (bath and shower). Prices are more or less the same as Residence inn but no b/fast included.
Size is about 1100 in square footage and has a fabulous interactive pool area for the kids. We've stayed in both and much prefer the space of Floridays, full washer/dryer/oven/equipped kitchen/balcony, TV + cable in bedrooms, flat screen in living room, DVD player etc. Best prices I've seen for it are on wshtravel dot com.
