I just booked the Dolphin at the AP rate of $189 for 4 adults, but was offered the Swan at the same rate. I just wondered why, since the Swan is more at rack rate and also at the Teacher/Govt rate. I know the Swan has queen beds, but have read that the double at the Dolphin are only about an inch smaller as they are larger than a normal full size bed. That is the only difference I can find. Why is the Swan normally more expensive and should I change it to the Swan?
