Here’s the thing: there are boats that drive you back and forth from the hotels to the parks, so you don’t have to worry about walking if you’d rather not.
RPR is closer to IOA and HRH is closer to USF, with the PBR being just a little bit further past HRH.
The way the thotels were set up, RPR was the cheapest of the three, then came HRH, then came PBR as the most expensive. But really there were only $30 price increments between them, so it wasn’t like a value resort vs a deluxe. They are all deluxe, just different levels.
Both HRH and PBR have water slides and poolside service. The reason the prices switched around with HRH being highger than PBR is that Loew’s no longer owns HRH.
I have never stayed at PBR, but I have walked around to check it out. I still prefer HRH above the others. But it’s still a matter of taste and which surroundings and theme appeal to you the most. You won’t go wrong with any of them.
