The answer to your question depends on what time of the year you'd like to visit WDW.
You most likely will not have a problem in January, the 1st two weeks of February, May, or September.
You will almost certainly have a problem if you want to visit during the two weeks that surround Easter or anytime in December.
Other times (if not associated with a national holiday) are usually possible if you are flexible with your choice of resort, room type and dates and are willing to use the waitlist. Many here report success in using the waitlist, but I suspect those of us who have not had success do not post as much as those who do, LOL.
Best wishes -
P.S. I do not own at VB. However, at the 7 month mark, a point is a point is a point. It doesn't matter whcih resort you own - everyone has an equal chance at remaining availability. As you no doubt know, at 7 months, it's "first come, first served" at all the
DVC resorts.
