Congratulations, I have been on a cruise ship and was so much fun
also the best thing to eat so you don't get sea sick is apples and crackers
(when I went on the cruise, the waiter told us this and he kept us filled with apples and crackers for our rooms, we never got sick)
we flew to Florida (visiting Florida Keys, Cozumel in Mexico, Cayman Islands and Jamaica)
was so much fun and would love to go on a cruise to Alaska
be sure you get off at any of the ports that they visit, so much fun!
