As someone who is here at WDW right now and very likely cutting our vacation short, if you can move your whole trip penalty-free to another time, do it. I know ADRs and FP make that challenging but in the big picture, I think you'll be happier than having a hurricane trip. We are thankful for the 2.5 days we have had here and that we were able to come at all, but still sad we will miss the special things we had planned for the rest of our trip (and all the unplanned "special" things that always come up too.)
Guests are already flying home early (loads of them on the monorail last night after Park close said they booked flights for today/tomorrow/Friday instead of the weekend.
We are supposed to fly home Sunday at 8pm. We are having loads of fun but also taking all the proper precautions so we are ready for all scenarios. We've rented a car and car seats, stocked up on food, etc.
We're waiting until the path is definite before we make our final call on when we'll head home.
Stay safe everyone!
