I'm not sure of other busy times, I bought
DVC in Apr. SSR , I had no problem hooking up my Feb. (including Pres. week) in May. That was in between 9-10 months out, I got just what I wanted, I Also called back in June and switched from 2 bedrooms to 2 studios....No problem!
In May I also hooked up the coveted 1st week of Dec. again no problem, at the 7 month date I switched and got 2 studios @BWV for part of my vacation.
I'm not sure how other high demand times will be or if you own at one of the smaller resorts. I think if you call @ 11 & 7 months out you will get what you need.......somewhere!
You would think that people "walking" their reservation would cancel the day they don't need as they call in DBD to extend their reservation.
This would make the days they don't need available almost immediately. I'm new to the DVC. I don't see where the big problem is. I hooked up both Pres. week and the 1st week of Dec. well inside 11 months with no problems.
Will it cause problems at different resorts? Maybe....No one knows yet! I'm just basing this on my limited personal experience......No problem!
