There are many things to like about the PPH. Unlike another poster above, I actually find the theming superior to the DLH (which feels like any suburban Hilton or Sheraton with a light-up headboard). Also, strangely, I've consistently found the CMs at the PPH to be the best of all three on-site hotels--happy, friendly, and helpful. I wish the club lounge had longer hours, but it's wonderful as well and generally less slammed with guests than the DLH or GCH. The pool is large, has a nearby bar, and a fun waterslide. Finally, if you can get a theme park view room at the PPH you will absolutely love leaving your curtains open and looking into DCA at all hours of the day and night.
