Sometimes people change plans while on vacation. With a 2 day cancellation, check to see if anything's ben cancelled up until the same day you are going to be there. Last time I was at WDW, my grandkids had had enough, but we had a 6:30 ADR for BOG. I walked over there to se what I could do and got in line behind someone who was back (again) to check for a cancellation. She was told no, no one had cancelled, and I spoke up and said I had one to cancel if I could and would be delighted to see her get it. It worked out for us, so you just never know...
