4 things you should know about Hurricane Dorian

By Marnie Hunter and Katia Hetter, CNN

Vacationers headed to Florida for the Labor Day holiday and the unofficial close of summer are in for a nerve-racking weekend.

Hurricane Dorian is expected to strengthen to a powerful Category 4 storm by Sunday and is likely to make landfall along the Florida or Georgia coasts on Monday after rolling through the northern Bahamas over the weekend.

Getting out of the storm's path will be tricky, as its path is still unpredictable with four days to meander over very warm water.

Flights

American Airlines has issued a list of Florida destinations that may be affected by the storm. Full details of itineraries that qualify are listed on the airline's web site.

The advisory follows several previous waivers issued by American Airlines for destinations in the Caribbean.

Delta Air Lines put out an advisory Thursday for cities in Florida and Georgia, following previous waiver options for Caribbean destinations.

Southwest, JetBlue, Spirit, United and Frontier have also offered waivers on change fees for itineraries involving specific destinations in the Caribbean and Florida.

As of midday Thursday, airlines had canceled more than 80 flights scheduled for Thursday and Friday, according to flight tracking site FlightAware.com.

"These are relatively small numbers, so we would not be surprised if cancellations increased closer to Monday morning as Dorian makes landfall on the east coast of Florida. We would expect flights to and from Orlando, Miami, and other airports in that area to be most affected," FlightAware said in a statement.

Cruises

Royal Caribbean cruise line's private Bahamian island, Perfect Day at CocoCay, will be closed through September 4 so that local employees can secure and evacuate their families and homes, the company said on its web site. Six itineraries had been adjusted by Thursday morning to accommodate the island's closure.

Guests that pre-purchased Royal Caribbean shore excursions for CocoCay will receive refunds credited to their onboard accounts.

On its website, Carnival Cruise Line listed a series of sailings it is monitoring and modifying out of Port Canaveral, Port of Miami, Jacksonville, Fort Lauderdale and Tampa in Florida as well as sailings out of Charleston, South Carolina.

The cruise line's online advisory outlines how passengers aboard specific sailings can sign up for text alerts for more information.

Disney Cruise Line posted an advisory about several sailings on its website.

The company said that Disney Dream will set sail as scheduled on Friday, keeping a safe distance from the storm. The itinerary may be modified, depending on the storm's path.

Disney Dream guests must call 866-325-3905 or 407-566-7032 by noon ET on Friday if they don't want to sail. They will have until October 31 to choose a new date. There's no fee to change reservations for this sailing, but there may be a price difference depending on the new trip.

The cruise line's August 31 Disney Fantasy sailing is expected to proceed as planned. The company is monitoring Disney Dream's scheduled September 2 sailing.

Amusement parks and other attractions

In Orlando, about 50 miles inland from Florida's Atlantic coast, Walt Disney World Resort opened its much-anticipated Star Wars: Galaxy's Edge land in Hollywood Studios on Thursday.

While Dorian's impact on the inland city packed with theme parks is not likely to be severe, Galaxy's Edge faces a potentially soggy opening weekend and scores of disappointed fans who may opt to reschedule their visits.

Universal Orlando Resort is monitoring the situation. "At this time our park operations and hours are continuing as normal. We have plans and procedures for serious weather that are time-proven and we will continue to make operating decisions as we learn more," the company said in a statement.

Kennedy Space Center Visitor Complex, one of Central Florida's most popular tourist destinations, expects to be closed Sunday and Monday because of the storm. The center is moving its Mobile Launch Platform inside, officials announced Thursday.

Change of plans

Some travelers are proactively canceling Florida plans.

Lindsay Wolf and her husband had planned to take their children, ages 8 and 10, kayaking and tubing on the Rainbow River with friends who had recently moved to the Ocala area, but the Atlanta family has made other plans.

"It was an easy decision to make to cancel the trip considering how large of an area the meteorologists are expecting the storm to make landfall," Wolf said.

She knew the rain would ruin their time in the sun, and the roads would be filled with evacuees heading north.

Luckily for her family, she found a hotel with an available room in Orange Beach, Alabama, "so we will still get sun and water," she said. "Plus, we will get out of there before any of the rain makes it there."

"The kids will understand one day, but last night our son didn't eat dinner and both kids cried their little eyes out."
