Both resorts have a great atmosphere for what they are supposed to be. HR is a party like vibe and RPR is a laid back relaxing vibe. My family could fit in well at either place, but the deciding factor for us is the pool depth at Hard Rock. I am going from memory here from several years ago, but i want to say the entire pool is no deeper than 3 feet. For that reason, we prefer RPR (although we would pick Portofino Bay over either of these two).
