I sailed on the Caribbean Princess last November and we docked at both St. Thomas and St. Maarten. Only tender port is Princess Cays. Would suggest you wait for about an hour (which would be 10 AM) and you should have no problem getting a tender. And, the ship is broken up into smaller areas so you don't get the big ship feel that you do on other ships (i.e. Voyager of the Seas). I didn't get a feeling of being crowded on the ship. Go and enjoy!
