There really isn't any way to see the waitlist itself or to know where you stand on it.
That said, if you have access to the Members' Website, you can check your "Vacation Details" to see if the reservation is posted there. If so, the waitlist came through and you will be getting your confirmation letter in the mail soon.
Once you are logged in, click on the link for "My Vacation Points". Then click on the link for "Annual Dues" and after that page loads, click on "Vacation Points".
Then scroll down a bit and look for the link "View Vacation Details". This last page will show all of your upcoming reservations. If the waitlist has come through, those dates will show as a reservation. If not, you'll just see the reservation(s) you were able to make.
Hope it comes thorugh for you.
