We just got back from our first Disney vacation -- checked out of the PPH today and I saw this thread -- I had to chime in because it's so similar to our thoughts on the property.
We stayed the first two nights of our trip at the Park Vue and our intent was to have a Grand Finale WOW by staying two nights at the PPH (ok, I know the GCH would have been the best route for WOW factor, but PPH was in the budget

)
The Park Vue greeted us with a very enthusiastic staff; convenient parking right by our room; a gift basket including wine, water bottles and snacks; free parking, wifi, breakfast & dinner; and a quick walk directly across the street from the DLR Harbor entrance. We thought it was great, but couldn't wait to switch to the "special" on-site hotel. We finally made it there, and....
The overall vibe we got from the PPH was that we were lucky that they let us stay on-site. As the OP said, it was a lukewarm, run-of-the-mill hotel reception (not the Disney WOW that we were kinda hoping for). The surf-board rice krispy treats are delicious and appreciated, but not much compared to the welcome basket we got at Park Vue. The parking at PPH is very cumbersome, especially if you have a lot of luggage or forget anything in your car and have to make the daunting journey to retrieve it

The elevators have their mellow moments and their nightmare moments -- it's usually when you're in the biggest hurry to get to the parks (like everyone else!) that you'll run into the biggest headache. And it will not be fun.
It was so nice to have a full breakfast and dinner spread included in the stay at the Park Vue -- I honestly was not expecting much from either one, but was overwhelmed with the quality and variety. And the in-room coffee was fantastic, real half & half and all! (Can. Not. Function. Without. GOOD. Coffee.) PPH has.... the worst thing ever calling itself coffee that I have ever put into my mouth. With fake powdered creamer.
Getting to the Parks was another pain, in comparison to Park Vue. Some pp's mention that contact with the "real world" may lessen the experience, which may be true. However, during our stay, the "real world" interactions included masses of other enthusiastic Disney visitors excited to cross the street and a couple of dudes with parrots that were pretty entertaining. On the PPH side, it's a long line to get into DCA through the GCH entrance, but they do open it at 9:15 instead of 9:30 (you have to go through Downtown Disney to get directly to DL by opening time). The trek to and from the PPH seemed to take a lot more time and effort than the jaunt across the street to the Park Vue. Our MM was during the PV stay, so it was a snap to rush across the street after breakfast, but we found the morning journey to DL to be much longer from PPH, especially taking the elevators into consideration. (After disgusting morning coffee!)
On the other side of the coin, the Park Vue is a motel, located on a very busy street. So it has that motel-y feel. You can tell that they do their best to overcome it -- the bedding is very nice, the coffee & condiments are excellent, the gift basket is wonderful, the staff is fantastic -- but it's an old motel property and will never have the "luxury" feel. However, you can totally feel the "heart"! On the other hand, PPH had the "luxury" feel with nice bedding and toiletries and hotel essence, but it totally lacked the "heart" when it came to the little details of making you feel welcome. It was basically more money for less convenience, in my opinion.
I wouldn't say that the PPH is awful -- if we didn't know anything else, we would have probably loved it. But compared to our experience at Park Vue, it seemed like the PPH was more money for less convenience.
