Although there is no way to guarantee if your waitlist will come through for that particular week, we have been very successful at getting our waitlists. We usually have two waitlists at the same time and if we put the request in online and the waitlist is fulfilled for the room size category, I do notice that I still have an active waitlist for the other room. This requires that I have to manually go in and deactivate the waitlist. Just keep checking emails or online periodically to see if the waitlist gets fulfilled.
