I have stayed at PBH twice and really liked it. The rooms are large and quite comfortable. I was upgraded to a deluxe room on both visits due to my Loews program membership, so the rooms I had were extra large and had huge bathrooms with a seperate bath/shower.
The resort grounds are amazing. Very beautiful and filled with lots of trompe l'oeil details. The Villa Pool is gorgeous and the Beach Pool is very nice as well. There is a third pool, but I have not seen it. The restaurants are good and at night opera singers appear on balconies overlooking the piazza to seranade the guests.
This is a sprawling property, so it may be quite a hike to your room from the lobby. There are, however, entrances interspersed throughout the resort so you need not return to the lobby each time you want to enter and exit.
I have not stayed at HRH, but I have a room booked there in September and I am interested to see how the resort compares to PBH in terms of quality and service.
