Oops I should have mentioned that the Trip Advisor poster indicated the Courtyard Marriott is the only 2 1/2* Priceline hotel in downtown Philly. Hope that info is correct. I can see where with experience the adding zones plan would work well, but as a novice it is hard for me to figure out which hotels are included in zones. I have a trip planned to St. Pete, FL in January, so I will keep practicing and hopefully get these tricks down. And, I will post back with my results, one way or another.
