For every passanger you find who will cruise again during hurricanne season, you'll find one who won't. It's a matter of preference. Before you jump in with the "it's no big deal crowd" do a search & at least read the horror stories.
My 1st cruise was in Sept b/c I too was lured by the prices. As a hurricanne approaced, my nerves were shot. I was a wreck. It turned out fine & we even had great weather but I doubt I'd do it again.
Cruise insurance is a must. Being flexible is alos important. I would also fly in the day before just in case.
