We are on Adventure for the ABC/St.M cruise. Renting a jeep in Aruba, Snorekling in Bonaire, Maho in St. Maarten---but what to do in Curacao? The last cruise I was on there, I was sick and never left the ship. We are two active adults with two 16 year old girls. Any suggestions for must do that won't cost an arm and a leg? (are other port days are already a bit costly with our planned itinerarys). Thanks y'all!
