I like them both, but I have more recently stayed at PPH (including just a few days ago). Now, the PPH has the same cute Mickey head bottles in the bathrooms that DLH has, so we were not missing anything there!
IF you do stay at PPH, beware of room 513!!! That is where we just were. It was almost level with the pool area. Anyway, the armoire had a drawer that was haunted and would not stay shut. It kept opening on its own and my friend tripped over it in the middle of the night.
Then, in the bathroom, the water from the faucet smelled TERRIBLE - it smelled like sulfur...or sewage...It was gross, especially when we turned it on to brush our teeth and had to rinse with it. Yuck! I have never had that situation at PPH before. Otherwise PPH is very clean and it looks a little newer than the DLH, but DLH has more fun stuff like the waterfall and koi fish pond. Also, PPH is convenient to take the "short cut" to DTD and DL/DCA, because you can just cut across the street to the GCH and walk through their lobby to get to DTD and the entrances to the parks.
But PPH was not on their game this time - the CM who checked me in forgot to give us our parking pass or tell us about early entry, as they usually do. She also spelled my name wrong on my Key to the Magic, AND she went ahead and connected my friend's key to my debit card, which I did not want her to do. I only wanted my key to be attached the the card, not my friend's, and they should have asked before they did that!
