(CNN) -- Leisurely vacations in the Caribbean have quickly turned into a race to get out of the region for tourists, planes and cruise ships in the path of Hurricane Irene.
The storm continued to pound the southeastern Bahamas and the Turks and Caicos Islands on Wednesday.
As the huge hurricane churned northwest toward the United States, it forced more than a dozen cruise ships to change their itineraries, CruiseCritic.com reported.
Those ships include the Carnival Sensation, which had been docked in Freeport, Bahamas, but is coming back to Port Canaveral, Florida, on Wednesday night -- or several hours earlier than scheduled -- to stay out of harm's way, said Jennifer de la Cruz, a Carnival spokeswoman.
"It's ahead of the storm and it's fine," de la Cruz said.
"We monitor the storms closely and make strategic changes to the itineraries to keep them away from the storm. The nice thing ... is that there are a lot of destinations in the Caribbean, so we have lots of options."
Meanwhile, Royal Caribbean evacuated CocoCay, its private island resort in the Bahamas, the cruise line said on its blog.
Port calls are not expected to resume in Nassau until Saturday, the Bahamas Ministry of Tourism & Aviation said.
The dangerous storm has prompted the ministry to recommend "strongly" that people with plans to travel to the Bahamas in the next few days postpone their trips.
It also asked tourists already there to leave.
"Even though the hotels in the Bahamas are fully prepared to accommodate guests under these circumstances, the Bahamas Ministry of Tourism & Aviation is strongly recommending that all visitors voluntarily evacuate the destination," the ministry said.
The Bahamas Hotel Association's hurricane cancellation policy is in effect for travelers who need to postpone or cancel their vacation in the islands. The policy allows vacationers either to use their deposits or payments toward a future stay at the same property or request a full refund.
