I have no answers, just my thoughts...
I've read it's not family friendly, just yesterday I read that it's not for adults who are older because it's for younger people.
It seems to be all over the place.
I don't know how young your "younger kids" are. Mine was 6.5 during our first Universal trip. On our themepark trips I have never, not once, had an issue getting the kiddo to bed. He is exhausted, and sleeping while brushing his teeth, LOL.
But at HRH we were right off a corridor and people were noisy. At RPR the last time we had the same situation. People are people, and the moment they get outside their door, they forget that doors exist and that doors go to hotel rooms and that people are in hotel rooms and that other people might not be on the same schedule!
People are people no matter where they are.
If you guys plan to swim, I suggest you hop to another pool. HRH isn't really a *swimming* pool; it's more of a lounging while sitting in the pool (it's shallow) listening to music pool. There's a good slide, but I'm not sure of the height reqs and not sure of your kids' heights.
Thankfully Uni allows pool hopping.
We've never had a problem with the distance from Portofino or Royal Pacific, so the location of HRH doesn't mean anything to us in reality. From our room, our bed, "sugar ants" in the bathroom (once we reported them maintenance took care of them quickly), the useless-to-us pool (if I'm in a pool I want to SWIM), not feeling that much closer to the parks, etc...HRH is *our* least favorite onsite resort there. But it's the fave of plenty of other people!
