Last year we wanted to add an extra day to our reservation at OKW when Hurricane Jean was going to hit. They were saying the roads would be closed at a certain point. We were staying at Cypress Pointe Grand Villas and wanted to get to WDW before that happened. I forgot member services was closed on the weekend - I had called my daughter at home to have her call them as she had the membership numbers there. I was really surprised when she called me back and said we were all set. She had called OKW directly after trying MS and they were able to add the day- It was probably the fact that it was adding the day to an existing ressie plus being a Saturday (lots of Points for that 2BR and worth every one of them to get into the Disney room before the storm hit) that enabled them to do it. I doubt that you can make a new ressie that way but maybe if you were in the area and just wanted a Saturday or Sunday night and they had space it could be done. They were putting up all the people from Fort Wildermess and those whose cruises weren't going out so I feel we were very lucky to get that extra night.
