Your girl is about to set sail, and I need your advice! I've never been on a cruise before, so what do I need to know?

I am departing from Mobile on Thursday for the Crimson Tide Cruise, and I am beyond psyched. We're travelling on the Carnival Fantasy, and the ship looks amazing--not to mention the fact that I get to be a part of the first-ever Crimson Tide Cruise! There are going to be theme nights, parties, and special events with some of the biggest names in Alabama Football. I can't wait.

I am a little nervous, as I have never been on a cruise. Will I get seasick? Should I pack Dramamine? How many outfits should I pack? What's the coolest thing to do in Cozumel? Should I purchase an excursion or just walk around the beach?
