I don't believe we are allowed to waitlist on an individual basis if the days we want are consecutive. This was a change implemented with the "New Reservation Policy" (based on check in date rather than check out date).
Jenny: You best chance of getting something will come at the 30-31 day mark. Members will cancel at that time if their plans aren't firm to avoid the holding account. If you want to stay on the waitlist after the 31 day mark, call MS and be sure they have that noted. Otherwise your waitlist request will expire. All waitlists expire at 7 days. If you still want somethingn after that, you have to call and hope you get lucky.
