I've stayed in both hotels three times now and I'll always choose the Swan over the Dolphin. Not only are the beds bigger in the rooms that have two beds, it seems the rooms are a little bigger as well. The Dolphin is so huge; it feels like a zoo. There are some things the two hotels share that are in the Dolphin (i.e. the gym, the buffeteria, etc.), but the Swan is so close, that realy isn't an issue. The Swan is a no brainer for me too.
