We don't have any tours planned at all. We've both done this route before several times, so we will probably just walk around, buy tacky tshirts, and find a local watering hole. We're old (40's) and the really fun excursions are outrageously expensive. (i.e. jeep trips, ziplining, etc) We'll probably just soak up a little local color and have some margaritas!
As for "on board" I am a gambler, so I'll be in the casino most of the time, while Sabrina likes to dance and do the disco stuff. We may see a show or two, especially the comedy shows, but not that show-girl stuff. Ick. Bottom line: we're on vacation and we're just going to veg-out.
How many are in your group? Any single men - over 40?
