My home resort is VB, but wanted to take a trip to Disney on fairly short notice, so last week I called for ressies for 3 nights at VWL Feb 10-13 in a 1BR. I first called and they told me I would have to wait list. I said I gotta think about it, talk to DW, and called back about an hour later. Rather than say anything about a wait list, I simply asked again about availability those dates at VWL and was told they were available, so I made the ressie. So yes, you can get in a DVC resort on short notice, even if it is not your home resort!
