Hi Wendy, Welcome to Cruise-Chat!
You'll love the Carnival Pride. As the others have said, you'll need something warm as you head down the coast. It gets chilly and really windy on the open decks. I usually take a long sleeve shirt and a wind breaker at least. Another thing after a few days in the Caribbean, you'll notice the chill more on the way back up. Have a wonderful cruise, and if you have a chance eat in the Steakhouse at least one night it is called David's.
