Unfortunately, the 2008 Hurricane Season has really picked up some speed. Hannah is now officially a Hurricane and Tropical Storm Ike has been named and given a projected path. Hannah is currently over the Bahamas, where my brother is scheduled to go on his first cruise on 9/8. Flying from Charlotte, NC, Hannah may cause some issues with their flight on 9/7. During hurricane season, you should plan on flying down a day early just to give you some flexibility.
For their 9/8 sailing on the NCL Sky out of Miami, I am most concerned about Ike. Hopefully, Ike does not mount to much and their cruise vacation will continue as planned. If you have an upcoming Caribbean Cruise, then keep checking back to CruiseSource. We have a link above for the Hurricane Tracker Page that I will update twice daily with updates from the cruise lines on impacted sailings.
