As this borders on an occupancy discussion, I'm going to go ahead and close it. To elaborate, DVC resorts do not provide cots or rollaway beds. It would be up to the guest to provide an airmattress or sleeping bag, along with any linens or towels needed. Extra towel packs (4 bath, 2 hand towels and 4 washrags) can be ordered through housekeeping for an additinal fee ($6 I think, unless it has gone up recently).
Some 1 bedroom units at AKV will sleep 5, having both a sleeper sofa and a sleeper chair.
