My boyfriend and I are first time cruisers and want to plan an excursion, but the more I research, the more I can't seem to pinpoint what would be best. We're both 43 but very physically active. (he's ex Green Beret, loves any adventure type stuff and I'm just crazy. ) He's very interested in seeing any ruins, I'd love to do some fun beach stuff and would really like a nice white, sandy beach. We'd be quite content to have some fun music, some drinks in our hand and lie around in a hammock, also. Any suggestions? Our main goal is to be budget conscious. Just moved into a new home yesterday and this was an unplanned, expensive, spur of the moment kind of thing. But Great!
