Here is a fun site that explains how to attempt the infamous twenty dollar trick (whereby you slide a $20 bill between your credit card and drivers license in hopes of getting a room upgrade).

It is a well laid out and simple to use site that explains how to attemt the twenty dollar trip and allows user comments that breaks down success rates at each Vegas hotel based upon those user comments.

You can click on each hotel to see what your odds are in pulling off a nice score on your next trip to the Holy Land.

Some of the user comments are pretty amusing and it's a good way to burn some time.
