We just got back from PPH in December so were pre-rehab. I thought the rooms were fine but the pictures I have seen of the rehabed rooms look awesome! We had already stayed at DH and GC so specifically wanted to try the third hotel and am glad we did. Most reviews that I read about the PPH complained that it was a long way. I have to say that I disagree. We did use several shortcuts. If you go out the back of the hotel and follow the brick path, you go right to the monorail. It is only a little further than the Bonita Tower at DH (Sierra Tower is definitely closer). The private entrance to CA is right across the street and very convienient. If we wanted to walk to DL, we just cut throught the lobby of the GC - saved about 7 - 8 minutes that way. My 7 yr old had no problem with any of the walking.
I have heard that the pool rehab at PPH will include a slide - it currently does not have one. That was always a negative before in chosing hotels but wasn't an issue in December! Personally, I love the DH but we saved over $400 for the week and that can buy alot of souveniers and churros!!
