I did ship tours from Carnival on both. Did Jolly Pirates snorkel trip in Aruba, which is a combo party booze cruise with 2 snorkel stops and a swim stop. Water was too deep and choppy for me to snorkel I'm experienced and it scared me but we had a blast dancing the limbo line, If I had it to do over again I would have just done a land tour or gone to Eagle beach. In Curacao Carnival had a 7 hour tour that took us to Boka Tabla where the waves crash, 2 pristine beaches for photos, 2 museums, and the Curacao Liquor factory. It was one of the best ship tours I've ever done! Amazing!:o Curacao is my new favorite port so much to see and do there! I hope to return!
