We were there last year during Frances - Disney is the best/safest place to be. You are inland enough to miss the worst - usually. Disney handles everything so well and it really is the safest place to be. When Walt built WDW he set a higher standard for building safety and Disney is the last place the electricity goes out - if at all.
Friday night things were starting to get in gear to prepare - ice (free) and styrofoam coolers (nominal fee)came out (this was at ASMo)- people were asked to start stocking food in their room should they have to close down early Sat - it was kind of crazy at food court. AK will close first for obvious reasons. Friday night I think the only places open were Epcot and DTD - we were at Epcot and it was like a ghost town despite being one of the few places open.
Saturday (we moved to Poly concierge) pool was open until about 1:30 - main house was open with characters, entertainment, and activities for kids. Everything closed down late afternoon, I believe. Prior to this they were selling box lunches for people to take to their rooms. Luckily, we were in concierge - we never were locked down in room - I heard WL guests in main bldg were also allowed to move freely about. We were very glad not to be in ASMo room. We had food, beverages, and full use of lounge the entire time. We hung out, watched TV, played games, etc. Disney ran movies 24/7 on the TV. We were kept informed through flyers left at the door - at all times.
Sunday things opened up around 4 or 5 - including Ohanas served buffet style not familty style - no characters. Monday, I believe just Epcot and MK were open with no monorail service. By Tuesday, I believe everything was back to normal.
Overall, all we lost was the day we planned to go to coast for a beach day - crowds were so low we could easily do everything we wanted in no time...got everything in - although some things like kiosks were down Friday and Monday. It was kind of a neat experience to see how Disney prepares and handles a situation like this - especially in light of the fact we were still able to get in all the Disney magic we were looking forward to.
Also, the weather on both sides of the storm was great - cooler and breezy - on Thursday there actually was a breeze at AK!!!
Hope this gives you some idea of what to expect.
