We like the swan better, but our ds are older. If you have younger kids the dolphin is probably better. Swan has queen beds and dolphin doubles. The dolphin is bigger, hence more walking back to room after big day in parks. Dolphin has more restraunt choices, they both share the boat transportation area, but the swan is the lst bus pick up. I like the swan double sink too. While one of the ds is showering in the am, I am using the outside sink to mix up a nice batch of koolaid or gatorade to take with us.
