Cruise ships
Norwegian Cruise Line: The company canceled its 10-day sailing of the Norwegian Getaway, which was scheduled to depart Thursday from Port Canaveral.
The company also changed ports on the 8-day sailing of Norwegian Sky, which left Miami on Sunday, the cruise line tells CNN. Instead of its scheduled Western Caribbean stops, the ship will now make stops in the Eastern Caribbean.
"The safety and security of our guests and crew is always our number one priority," the cruise line said. Shore excursions booked through the cruise line in affected ports will be refunded to guests' onboard accounts.
MSC: The company has changed course on at least one of their ships and is monitoring the possibility of changing others, a spokesperson tells CNN. The MSC Seashore, which was originally scheduled to be in the Western Caribbean has been rerouted to ports in the Eastern Caribbean.
The cruise line is also monitoring the MSC Divinia, which left Port Canaveral on a four-night sailing to Nassau and the Ocean City Marine Reserve on Sunday. MSC says both cruise ports are outside of Ian's projected path, but advised passengers before leaving that conditions could prevent the ship from returning on Thursday. The cruise line says if there is a delay in their return, the cruise will be extended at no additional cost to guests.
The cruise line does not expect Ian to impact the MSC Seashore, which is set to depart from the Port of Miami on Saturday, October 1.
Carnival Cruise Line: The company has announced changes to its schedule. With the ports of Tampa Bay, Canaveral and Jacksonville affected by Ian, the following sailings have been canceled:
• Carnival Paradise: Four-day cruise from Tampa on Thursday.
• Carnival Elation: Four-day cruise from Jacksonville on Thursday.
• Carnival Liberty: Three-day cruise from Port Canaveral on Friday.
Guests will receive a full refund and a 25% future cruise credit, Carnival said.
The following ships have changes in their schedules and ports of call to bypass the storm and its effects: Carnival Liberty, Carnival Horizon, Carnival Sunrise, Carnival Paradise, Carnival Elation, Carnival Ecstasy and Carnival Glory.
National and state parks
All National Park Service employees were evacuated from the Dry Tortugas National Park, on the western end of the Florida Keys in the Gulf of Mexico, before the approach of Hurricane Ian, according to NPS spokesperson Allyson Gantt. No employees will be riding out the storm.
As of Tuesday afternoon, dozens of Florida state parks were closed, including Alafia River State Park (Hillsborough County), Bahia Honda State Park (Monroe County), Delnor-Wiggins Pass State Park (Collier County), Don Pedro Island State Park (Charlotte County) and Lake Manatee State Park (Manatee County).
