I was annoyed by the waitlist limits as well, and got tired of going to the website to check availability, so I wrote a script to do it for me. I actually got four nights at VGC for Christmas break when a cancellation popped up.
When I saw how many people had the same problem as me, I made my script into a website. It can email you when a room comes available. Maybe you would find it useful? You can find it at ******.com.
