We took the 4 night cruise to the Bahamas and totally over dressed everynight, and got really into the pirate themed night (even had fellow cruisers think we were part of the cast..LOL) I have the best family pics from that vacation. It is YOUR vacation, do what you want with it. As I told my family, we dont know anyone on this cruise, lets have fun and be silly. My kids have the best memories. We are no gearing up for a 7 days cruise next year. Have fun!!!
