I was just on Grandeur of the Seas last week!
Great ship! Only complaints we had were how they handled tendering in Grand Cayman, the "latte-tudes" shop (and the clueless people that worked there), and our last day when we were trying to get off the boat. I can't remember in which of our ports (Cozumel, Grand Cayman, or Aruba) where they made an announcement trying to advise cruisers not to rent mopeds. They weren't saying not to, but found it to be in best interest of people renting them not to. Hope you have fun! Please give a review when you get back! (of both Bermuda and the ship!)
