That's an interesting thing your writting there. How and where did you get that voucher? And how much did it cost?
Last time we were there we didn't know about that so we just bought everything.
A few days before arriving at Half Moon Cay an information package for that port was left in our cabin. Included was an advertisement for an unlimited bar/drink package for about $30 per person, if my memory serves me. I do recall that I would break even if, during the beach break, I was served 5-6 drinks. Which I was was, and very much enjoyed, since I had them delivered to me and did not have to line up. The drink voucher was purchased through the onboard front desk and added to my account.
