Checkbook Magazine says it found a loophole around the system.
According to Checkbook, the trick is to just pick another neighborhood close on the second go by that you know doesn't have a four star hotel!
This usually defaults you back to the neighborhood you first selected.
Using this trick, Checkbook got a room for $72 a night at the 4-star Loews hotel in Center City.
Compare that to $198 quoted on other discount travel sites!
Checkbook also got a room for $58 a night at the four-star Hyatt Regency in the Chicago Loop!
