Sounds like the "booze" cruise. I had the same problem when I first arrived. I thought the "booze cruise" was the same thing as the "boobs" cruise. The "booze" cruise is decent but not really worth it. I was upset that they charged for food as well.
Honestly, I think I might've asked if it was the Boobs Cruise + the guy at the desk said "Yah, Boobs Cruise" But with his accent maybe he did say Booze cruise. They DO sound very similar! :huh:
