We are in our early 30's, and went with 4 other couples (ages 36-59), several were cruise virgins :-)
We had a great time! I was a bit concerned with the ship being older...but no worries (that I found). Food was great, our waiter Dennis, and steward Gusti were top notch!
We flew from CMH to MCO, onSouthwest the day of the cruise, arrived at 10am, Michael with VIP Limo was waiting for us with his stretch limo, took us to walmart for us to buy last minute things, and our wine and drinks. We arrived at the port, had to wait to drop us off about 15 min, dropped our luggage off and we were headed inside!
