i'm glad someone asked this question. i was thinking the same thing. i am already in the planning phase of possibly celebrating my dd's 3rd bday at DL next may....and i was thinking of staying onsite. i know we can afford either DLH or PPH...but i keep thinking that if we stay off-site, that would be more cash for souvies, eating at DL, character breakfast, etc. i don't know...my sister and her family went to DL this past may and they were going to stay at DLH...but figured out if they stayed off-site, they could go to DL twice this year...and they are...they are going again this october and staying off-site again. hmmm...i guess i have a few more months to think about this. if i got a PIN in the mail, i might consider staying on-site

wishful thinking!
Only PIN I've gotten for DLR is for the Jolly Roger. A place I would never stay at.
I've stayed at PPH and offsite (and actually at DLH but I was a kid and barely remember anything beyond adjoining rooms, scrambled eggs, and my mom getting a brutal migraine from the teacups).
I prefer offsite. I prefer more money for souvies and food than spending it all on the room.
Since we go relatively often I don't really feel the MM days are a must (especially since it's difficult waking hubby and son up for them...in real life I sleep in but at Disneyland I do NOT) so they aren't worth paying more for.
I do not like walking through DTD to get to the parks, b/c I have a son who wants wants want everything and asks asks asks all the time, so I prefer to stay on Harbor and avoid that (until we get in the parks).
When we stayed at PPH, the monorail was down the whole time, so we never got the benefit of going by monorail into the parks.
When we checked into PPH, relatively late (mysterious black hole caused our 7 hour drive from my dad's in Santa Cruz to be 12 hours), we were put in a room that smelled of cigarette smoke, had a dirty towel in the hamper, and had no toiletries. Their princess good night stories on TV was ALWAYS Snow White, and I can't deal with her voice.
The elevators took ages and I nearly fainted when I took the fast, glass, elevator (so even when DH and DS took that one, I took the slow enclosed ones).
I just didn't enjoy the onsite thing enough for it to be necessary.
Walking back to HoJo on the Disney side allowed us to hear Disney music the whole way back, and we could hear the music like we were in the parks while standing in the parking lot (walking back from dinner on a blocked out day). It felt more Disney to us than dealing with the commerce of DTD!
I'm sure we'll stay onsite again just so I can speak with knowledge of the others, but it would have to be a kick-booty rate at GCH. I won't pay those rack rates unless it's a Westin or higher in Hawaii, LOL. (and HoJo's has Westin-style beds!)
But the cost/benefit analysis for us means that offsite will usually win for us.
OP, if you like PPH stick with it. If you want to try something new, try something new!
