well, I cant really comment as I have only 1 PH stay, and it was this past weekend.
The DC PH was nice. I was little disappointed. I had 3 rooms. I selected food and beverage amenity and each room received a bowl of 3 oranges? Funny, I was at the grocery store tonight and bought a dozen for $5!
A source at the hotel also told me by the end of 2012, there will once again be a NYC PH and a Miami PH
