My Mom and I are booked on that cruise. She's 78 and I'm 54, so we're not spring chickens. We've each been on at least 10 cruises, but this is our first on Carnival. We took it because we wanted a short cruise and wanted to see Key West. I have booked a Swim with the dolphins when we stop in Cozumel as the ship only seems to offer the Encounter. We'll be driving down to Florida from upstate NY as we plan to attend a couple of Elderhostels when we get back to Florida.
