Last summer, we stayed at HRH, but swam at PBH, and checked it out in general. I hated the PBH pool -- very little landscaping, and all of that rock and stone seemed to reflect the intense sunlight -- made the heat just about unbearable. The HRH pool, on the other hand, is lushly landscaped; the layout is much better, too. I couldn't comment on the rooms, since I didn't see them -- but the entire layout of PBH seemed awkward and hard to navigate.
HRH is adjacent to Unversal, too -- a huge bonus, IMHO. Yes, PBH is across the (very busy) street, but when it's 98 deg. outside, every extra step is too many. There were plenty of famlies, too -- HRH seems to have a reputation of a party or singles-type place, but that's not the case. Just a pleasant,well-run place!
