When is your trip? They are currently working on PPH and haven't yet finished, which means there are some things they don't currently have, like dining (although I do think I read that they opened something recently). There is the newish entry into DCA that is very convenient. The theme park view is pretty awesome.
I *personally* don't care a whole lot about the view because I usually go to bed after going to the parks all day. I don't like that there are no grounds at PPH, just parking lots and such and you're fronting a public street with traffic. I've not been to the pool level in many years so I can't comment on that area.
On the other hand, DLH has just opened up new DVC rooms and it may be a lot more crowded--don't know as I've not been since DVC opened. I think that would mainly impact the pool and dining. Dining is pretty limited anyway.
But DLH has beautiful grounds and feels more like a resort. If you don't care about the pools and palms, shops and memorabilia and so on, then it probably isn't worth the extra cost (if it costs more). I usually request a standard room in the Adventure Tower, which means your view is blocked by trees or something but as I said, the view is not of paramount importance to me. I just like being closest to DTD.
