I rated them on 6/8/12 based on my stay then. I can't believe I didn't login to finish it. I LOVE the HRH! Fun gaming, awesome rooms, near perfect service (the hotel, not the restaurants - there is a difference, thus 4 instead of 5 stars).
My biggest tip is to stay in the Casino or HRH tower. The Paradise tower is nice, but it's a long walk from the casino.
I've stayed at the HRH numerous times. It's definitely my favorite hotel in Vegas.
