The Swan has queen beds to the Dolphins double beds. The Swan has 360 sq. ft. rooms to the Dolphins 380 sq. ft. rooms. Right now both are undergoing renovations, and the Swan will be done first. They are getting "Heavenly" make-overs, with new beds, linens, artwork, and a softer decor. As to which one is better, you wouldn't know the difference except for the beds and room size of each resort. These are sisters, and while they're not twins, they are a lot alike.
