I'd never get a plane reservation without having a hotel reservation first.
We did stay at WDW in June when TS Arlene hit the Gulf Coast. We were supposed to leave WDW on Friday and Arlene was hitting Gulf Shores, our next destination on Saturday. We called OKW to see if anything was possibly available to check in on Friday for three nights. They said they didn't have studios, but they had one bedrooms. So the next AM, we headed over to OKW. But, we didn't have enough current year points to make the reservation. So we waited for MS to open, called them, switched current year points from our Jan 06 reservation to this new one, borrowed points to put back into the Jan 06 reservation. We stayed for three nights in a one bedroom at BCV.
Funny thing was, when we made the June reservation in January, BCV wasn't available, so we took SSR.
But we were prepared to stay just about anywhere using cash if we needed to.
