If this thread is for Jamaica in general, I would like to hear more too. If it's to see if TB was blown away, that's another story. As for the kids and staff, they stayed at the same place as the disaster teams, so if you hear the disaster teams were injured, etc., then there is cause for concern. If not, keep the faith that those kids are going to have some stories to tell about living through a hurricane.
Why didn't they all fly out? Ever tried to get a flight out of an area threatened by hurricanes? Not only are flights sold out in/out of Jamaica on a regular basis by tourists, finding a flight that isn't sold out or cancelled is the challenge. Finding a flight that isn't going to Miami is another. From the last hurricane, flights are still sold out from people waiting to go home from most Florida airports.
I personally would have chosen to find as safe a place to stay as I could and ride it out rather than standing in line at an airport. Would disaster relief workers chosen an unsafe place? Only time will tell.
