Familyof14, actually when I was there I noticed there were six floors, and if you looked at our room from the piazza, there were two above us. The lobby itself is on the 3rd floor. I myself had a WONDERFUL stay there, with a wonderful deluxe room.
The bathroom was fantastic. With 5 adult size people though, if everyone likes privacy while showering and shaving, etc. then you may want HRH that has a sink outside the bathroom with shower. PBH has everything, including two sinks, a separate shower and tub, as well as toilet in one big bathroom.
My rate per night was 189 for deluxe, and at the time was cheaper than either HRH or RPR. I think they needed to fill rooms at the last minute, because this rate came up fairly close to my visit, and it was during spring break time.
