Toni. I like that "young" age. I am a 57 year old male. I am retired and travel a lot, primarily scuba diving. I have been to Cozumel many times and to Playa (the beach is topless, by the way so let mom know). You'll have a great time.
I have always wanted to get into the cruises and have lots of time, but I just haven't done it. Enjoy. Don
