I depends, some units have the new style sofa sleepers, and others still have the original. Even the original sleepers ca be comfortable if they've been used gently over the years. While the newer style sleepers are "fine" for adults, and pretty comfortable, they are still not as comfy as a real mattress. And I think that would be true for all the resorts. The master beds at OKW are quite high off of the ground, so youngsters really are probably better off on the sleeper sofa. If your worried out exterior access, the outside patio has direct access from both the living room and master bedroom, so it one of the kids has a tendency to wander, they are about equal as far as security.
