$30-$40 I would say yes if you like the atmosphere at HRH, which we do. My kids (8,10,12) absolutley love the place, they say it's cool. I haven't actually stayed at the RPR, but I did attend a week long conference there and I choose to stay at the HRH and commute to the conference everyday.
It's much easier to get to the parks from the HRH and the Palm restaurant is very good. The pool with underwater music and the general atmosphere is nice. If you have kids and can get a deal I recommend getting one of the 500+ sq. ft rooms that have a sleeper sofa plus 2 queen beds, it gives you much more space to spread out !
Wherever you stay you should try Mama Della's at the PBH, it's very good italian restaurant.
