If you go on a cruise and don’t gain at least a couple of pounds, either you’re doing it wrong or you are blessed with amazing metabolism. For most vacationers, one of the highlights of cruising is indulging in the vast array of plentiful foods on board, and Carnival’s new Mardi Gras ship fits the bill. I’m pretty sure I gained at least a pound while attending the Sip and Sea preview event. And I was only on board for six hours! Was it worth it? Absolutely. Ready to ride! Bolt is the first roller coaster on a cruise ship.
