It never hurts to carry a few travelers checks, you can cash them right on board, no problem. At least that way you don't need to carry so much cash. You only need cash for the casino, tips and what every you want to buy on shore.
Hello Jen, here's something to think about. I got all my cash via the casino. I don't know if people are aware of this or not. But the casino (Voyager of the Seas) will give you cash when you use your SuperCharge card, no fee. This was great for me!!! It was an ATM machine w/out the fee. At the end of the cruise they charge everything to your credit card or you can pay the bill in cash/traveler checks. I don't like fooling w/ traveler's checks nor carrying large sums of cash. So the nights before the excursions I would hit up the casino for $100 or so and use the cash on the islands. Another great convenience offered by RCI.
On my last two cruises I have quit using Travelers Checks. With the large number of ATM's available, the need for Travelers Checks has become much less.
I have about $100 in cash on me when I board the ship and use the ATM's in port to get just enough local currency for my purchases while in port.
Use your Visa card for larger purchases.
The Cirrus and Plus cards are accepted throughout the Caribbean.
Most of the onboard casino's will let you put a few hundred dollars on your onboard account if you would like to gamble. If you are a winner you can pay back the original amount you put on your account and they will take the charge off of your account.
I find the question to be remarkable. It really makes a lot of sense to take your cash with you in the form of traveler's checks. Cashing them on board... or in the ports, is easy and you won't pay the exorbatant rates the cash machine folks get out of the Country, or for that matter, on board. Use your credit card for any purchases you make on the Islands (substantive, that is) for a whole bunch of reasons. It you want to buy something of value and the store won't take cc's... suggest you move one.
Believe it or not many of the crew members don't think they are real as they have been given 'fake' bills in strange denominations in the past by some wiseguy types and rather than risk embarassment just toss two dollor bills.
