My aunt/uncle and 3 cousins are going with us to WDW this summer. They are booked at the Dolphin on a govt employee rate, but I called today and was able to get a ressie at BWV studio for them. We are at BCV the same time, so I booked 4 of them at BWV and put one of the kids in my room. (Chances are better than not that at least one of them would be staying with us anyway.) I also waitlisted BCV for them So, my question: are the rooms at the Dolphin that much bigger (or any bigger) than the rooms at BWV or BCV? We are not lounge-in-the-room types, but want to stay here for location, SAB, location, good eateries, location, etc. I'm thinking that if the rooms are similar in size and the Dolphin allows a roll-away, then we should be able to fit a twin mattress in the room so everyone can sleep comfortably. I have an Aerobed mattress I could take that inflates/deflates quickly so it could be put up at night and then put away during the day without much trouble. I don't mind it being tight - we're from large families and are use to that - but don't want them to be wishing they had kept their room at the Dolphin either.
