I also prefer the Swan. It is a bit quieter. My room at the Swan seemed a bit cleaner - but that could just be by chance. You just have to walk under the walkway to be at everything at the Dolphin (laundry room, but I was glad I had the stroller to put the pop up laundry basket into, so I didn't have to lug it myself). Also, you can get queen beds at the Swan, doubles at Dolphin (I had a king bed with a pullout sofa though, so it was fine, as I like a king bed and one child slept with me, the other on the pullout sofa, it was just me and the kids that trip). My room with the king bed and pullout sofa at the Dolphin didn't let the sofa pull out (too small) so I had them remove the sofa and bring me a rollaway (again that trip was just me and the kids so it was fine). The Swan is smaller, so sometimes it's full before the Dolphin.
