Been to Swan and Dolphin in the past. I agree that the rooms in the Dolphin seem bigger and my wife clamins that there is more storage for stuff. It may seem bigger because there are 2 double beds in the Dolphin, instead of the 2 queen beds that are in the Swan. I have 2 sons... 4y and 2y old. We stayed in the Swan and it seemed just a tad bit crowded with the crib in the room. We are planning on going back in Jan 09 to the Dolphin as opposed to the Swan with a newborn because of more room.
