I agree with those who ask why in the world would we want to disembark one day early. Well the reason being is that we are doing a back to back cruise out of different countries. Cruise #1 starts and ends in Barcelona. Cruise #2 starts and ends in SouthHampton. Now my wife and I are well seasoned travelers and cruisers, so we did know exactly what we were signing up for when we decided to see if we could actually pull this off. Debark in Barcelona starts at 7:00am...our cruise departs on the same day out of SouthHampton but not until 8:00pm at night plus we gain an hour traveling from Barcelona to London....so it is totally doable...but then we thought...what if we spend an extra day in Malta as opposed to spending a day at sea and so that is why I asked. THe ship does embark and debark out of all of the ports except for Valetta, Malta. This is why we asked....but probably should call MSC to verify. Yes, we know it is crazy to try this...but we absolutely love crazy adventures 🙂
