we are a family of 4 (2adults - 2 teens-16 &15) right now booked for 8 days at Carribean Beach. I picked CB b/c I love the beach and the carribean, but now am having 2nd thoughts to switch to coronado springs to have the queen beds. Its only total 39 dollars more to switch, is it worth it to have larger beds, or do we bring a blow-up mattress and have the kids take turns sleeping on it and moving it out of our way during the day? thoughts? anyone?
