Hurricane Dean's presence in the Western Caribbean has forced over a dozen cruise ships to quickly change their itinerary towards the eastern side of the Caribbean this week. The storm, currently moving as a Class Three hurricane through the Yucatan peninsula, has affected Carnival Corp. (NYSE: CCL) the most.

According to the company's site, as of Sunday, August 18th, the itineraries of over ten Carnival ships have been altered, forcing them to dock in Eastern ports-of-call or cancel a part of their stay. CruiseCritic.com has reported that a dozen of Carnival's ships were impacted from Dean. The company could not be reached for comment. Only three Royal Caribbean Cruises Ltd (NYSE: RCL) ships needed to steer clear of the storm.

Despite many weather stations calling Jamaica "Ground Zero" all weekend, the island nation received a glancing blow on Sunday. Gene Sloan of USAToday's "The Cruise Log" reported today that Royal Caribbean will be the first to test Jamaica's waters on Wednesday, as originally scheduled. Carnival's spokesman Vance Gulliksen told Sloan their line expects to resume calls in Jamaica next week and plans to return to the Caymans as early as later this week, but is "awaiting final confirmation."

The major question is the impact of Dean on Cozumel and other Mexican ports on the Yucatan Coast. Check out CruiseCritic.com's Hurricane Zone for an updated list of the damage reports.

In today's world, people rarely carry large amounts of cash on them. People have credit cards for large purchases or even debit cards to access their checking accounts. ATM machines are on every urban street corner in America. But what happens when you're not at home in that urban setting? What do you do if you're on vacation?

I recently went to the Caribbean with my wife. We knew that most places would accept our cards but we questioned the exchange rate. Eastern Caribbean money isn't that strong in comparison to the U.S. dollar ($2.60 EC to $1 U.S.) and we knew that our credit cards would charge a service fee for purchases made in EC dollars. My wife, whom I consider a "world traveler," has always gone with the traveler's checks and prepaid card route. She would cash the checks in at the hotel and use prepaid cards so she wouldn't put her personal accounts at risk. I always used my credit card on vacation. Before our trip, I was sent to the bank to pick up a pair of prepaid cards and some traveler's checks.

The July issue of Money magazine has a great article regarding the best way to keep exchange costs to a minimum with today's weak dollar.

I found out she was completely wrong - a month too late.
