I never stayed at either but will have our first Dolphin experience next month. We chose the Dolphin because I have read that you get more of the hustle/bustle feel there. The Swan is quieter. Also, the Swan has Queen beds, the Dolphin doubles. From what I have heard, the doubles are a little bigger than your standard double ( I forget the term for them). I stopped in the Dolphin last year at Christmas time and I loved the lobby with the huge tree in it and enjoyed one of hte restaurants we dined in. People do seem to love each equally so this may be one of the decisions that you can't go wrong, either way you decide! Have fun!
