We went on a b2b Med/Trans via the Magic and Disney treated each cruise separately. We took two bottles each of wine in our luggage for the first leg and none on the second...nursed the bottles through the 19 days. Stayed in the same room for both cruises so did not need to take any luggage off the ship during the switch-over. Believe we could have brought aboard another two bottles each if we wanted to buy them in Barcelona for the last leg.
