We have been seriously thinking about purchasing DVC points and I thought we were about ready to "Take the plunge" and all of a sudden, my hubby starts getting all concerned about the sofa beds not being comfortable. My son is only three right now, so I can't exactly ask him how he feels about the idea of sleeping on a sofa bed for all of our vacations! Are they really uncomfortable or are they okay? My son is very big for his age, and I expect he will always be a big guy, so answers about the comfort level from anyone who is not "petite" would be the most helpful! Thanks!
