I was also at WDW (staying on points at the VGF...reservation was 9/24-10/1)...HUGE kudos to all Disney personnel on how they handled Ian--in all ways. It was truly amazing. But with respect to changing reservations: there was LOTS of talk among us guests about the need to extend a stay due to the hurricane. We talked to a fair number of people who were scheduled to check out Wed or Thurs or Fri--the Thurs check-out people seemed to have had the most trouble--apparently the earlier someone tried to make changes, the harder it was. By Thursday late afternoon, though, the situation seems to have stabilized. I know I got very nervous because the airport was still closed with no news about when it would reopen, and the hurricane was projected to head north and possibly impact my destination. So I went over to the front desk (around 4 Thursday afternoon) and they couldn't have been nicer--it took about 15 minutes and the end result was they put a hold on my room (same room, no moving required) for Saturday night (10/1) in case the airport hadn't opened by then, or if my destination airport closed down (or if my flight canceled). They checked w/me to make sure I was ok with the need to borrow points if it turned out I needed the room. Then they told me I could stay in my room (in the Big Pine Key building) if I needed to; just to let them know as soon as I found out what I would need. Amazing! So, yes, the extra night (which I turned out not to need after all) would have cost me points. But they announced early-on (don't remember if it was Tues, Wed or Thurs) that MS would be closed and that no new bookings would be accepted until 10/3...when I went to the front desk, I just asked "what should I do?" The idea of putting the hold on the room (after asking me if that was ok w/me) was their idea.
I can't rave enough about great Disney was during the hurricane. They were completely fantastic. They had good food, at reasonable (even low-cost) prices, available for each day, all day. They had in-the-lobby entertainment in the main building (both for kids and for adults). They put board games out in the lobby area of the Big Pine Key. They were incredibly helpful. The sundries shop remained pretty much fully stocked. The shops stayed open (mostly; a few closed--like Basin on the second floor). The clean-up was amazingly fast...pools were open by Friday and all the walkways were free of debris (of which there was a LOT) by Friday afternoon.
I just was on the website trying to make a change to my January reservation, and it shows no availability for any room of any size at any resort for my dates--I'm guessing the system hasn't quite recovered yet from the hurricane-related changes (at least I hope so; I need an extra night in a one-bed at SSR in mid-January)...
Anyway, major gold stars, kudos and praise to Disney...they were amazing.
