We are using points from a friend and staying in a Beach Club studio. It'll be dh and me with 7,4 and 1 year old. The baby will be in a pack n play. Do you think we'd also be able to fit one of the other kids on the floor in a sleeping bag that we'd bring with the sofa sleeper open? This seemed perfect when we booked it but now I'm getting concerned about the 4 and 7 year old getting "decent" sleep in the sofa sleeper together!
