Glad to know that it's your first cruise. You're going to love it. I went on my first cruise on the Glory two weeks ago, and had lots of information from all the lovely CruiseMates; and I absolutely enjoyed my vacation. So now, I'm another cruise-addict convert; I'm hooked and can't wait to book my next cruise!
I like the article that MikeM posted. It truly describes the magic of a cruise vacation.
Hope that you have the time of your lives!
