I'm thinking it is a misreading of some sort. I haven't heard anything about it. As far as I know the Fantasy left Charleston at 16:00 hrs this evening on schedule. Sailwx is still showing her way down the coast in Florida between the Bahamas which would be impossible if she is on schedule.
Okay, I just spoke to a staff member of one of my favorite restaurants in Charleston. Fleet Landing that is beside the pier. The Fantasy left shortly after 4 pm today - on schedule.
CruiseDad, hope this helps alleviate any worry about your daughter.
Something wacky must be going on with the tracker/locator.
