The value resorts have double beds which sure don't work for my family anymore.
When my kids were little (under 8) we could have one sleep with each parent and that would be sort of comfy. My youngest kicked in her sleep so that wasn't always good.
If you want to stay value, you could squeeze a twin size air mattress in the spot where the table and chairs are (you'd have to move them - maybe near the door?) and during the day stand it up so you could move around the room.
Really I would just get a moderate room with the queen size beds so one adult and one kid could sleep on each bed. The extra space in the room is also nice as are the pool slides and the hot tub at the moderate resort.
The value resorts don't have pool slides or hot tubs.
Good luck deciding!
