Just cancelled our trip to FLL on the 15th. Even if they don't get hammered, I feel like all of Southern Florida is going to be in repair mode for the next few weeks and will need all resources going towards helping people who live there. Don't want to get in the way, and better safe than sorry. They'll get my money next year to help with rebuilding.
I haven't done that yet. 5 days out for my trip starting 9/16 is 9/12. I'll decide then.
