double check your limit before you leave home, some cards have limits on them, you can request a limit hike i think by going to the bank. Just make sure you have enough money in the account to cover your expenses before you leave home.
sure they might not let you off the ship, but they have a heck of alot of dishes to wash and potatoes to peal and garbage to haul off and beds to change and tables to clear and decks to mop and they don't let you share in the tip pool (smile)
adnor, when we were on an NCL ship a few years ago we had a rather large bill (there were 16 of us) with shore excursions, drinks, items bought on board, our bill was a little over 6,200. Although the card was debited nightly, when we got home I found NCL still had about a 2,200 hold on the account. I had to call NCL and connect 3-way with the bank to have the hold removed. I didn't understand since the card was debited nightly why they should have this kind of hold (after all on the last night I wasn't going to spend 2,200). It is my understanding however that all cruise lines do put an additional hold on the card. Sooo, you might want to remember that your account could still have a hold on it even when you return. I don't know how long it would have taken NCL to lift the hold had I not called.
