That's a tough time to get right now. According to other posts, there are many ahead of you for that time. If you haven't already, consider making a back up reservation somewhere.
Did you waitlist for the entire time or by individual day? It's more likely that waitlisting by individual day will be successful, but you do risk not getting all the days and thus having to move.
The best chance will come 30-31 days prior to arrival. That's when anyone whose plans aren't firm will have to cancel or risk having their points go into the holding account. If your waitlist hasn't come through by then and you still want to be on it, call MS and tell them so. Otherwise, your waitlist request will be dropped. At 7 days prior to arrival, there are no more waitlists. You'd have to call every day to see if something opened up.
Good luck to you and all those waiting!
Best wishes -
