I was at Disney for Hurricane Francis in 2004. *stuck*(lol) in the Contemporary Tower for 2 days (well 2.5) while the parks were closed and the storm rolled through. I don't know if they closed for Charley or not and Jeane came through at night. anyways - Disney had food available for guests, but it was NOT free. We still had to pay for those boxed lunches and buffets. It's kinda eerie eating meals at Chef Mickey's without characters and paying near full price. The food was the same, just no characters. The discount was only around $5-7 if memory serves.
We were comped tickets since were were on a LOS package, but the food definately wasn't free.
