I have been staying at RPR for 5 years now, have did 2 split stays with PBH as well, HRH is just not our scene, although DD might like it.
PBH was more for adults [IMHO] and not much happening for DD, while RPR is always something going on that she can join in.
If no kids i would go for PBH everytime, although still love RPR themeing.
While RPR is usually cheaper ,its still first class, and like Wayneg said PBH can be cheaper, as it was for us last July,you just need to keep checking
