Given there are still months left you have a shot. But I also think it depends on when you waitlisted. There could be 100 people waiting in front of you so it might be hard.
There are only 136 villas in total at VWL and you are looking at probably one of the busiest times of the year. Depending on what size of accommodation you are looking at, I'd say the odds aren't all that good.
Still, there is no charge to waitlist, and no harm in giving it a shot. It may work out for you. Good luck!
It depends a little bit on what you are waiting for, example 1-br versus studio or 2-br. But in any case, the chances are slim. But if you got onto the waitlist early, then you might have a shot around the 30-day point.
