I'm not your typical Vegas-goer as I don't do the club scene and am usually here for conferences. HRH has a reputation for being pretty crazy with their Rehab party - from the looks of it, I think it certainly lived up to that reputation.
Here's a review from someone who was sober the entire time:
Pools: I think that they have the best pools in Vegas. If you're like me, then Sunday morning is probably not the best time to go...but anytime during the week, when it's fairly empty, the pools are like a glimmering oasis of blue. I think there's 10 or more. I know that they close early, but I was able to walk in and dip my toes in ... I saw some people swimming so as long as you're discreet, maybe it's possible to do some pm swimming :)
Food: I only ate at Pink Taco. Their happy hour was ridiculously cheap. We sat at the bar and ordered one of everything (giant fatties). They seem to do chicken the best (skewers). I also recommend the tamales.
Room: We stayed in the Paradise Tower. It's set further back from the hotel. The room is very rock 'n roll - dark wall paper (very gothic) and I think the most comfortable bed...ever? I've slept in some nice beds, but wow...after a long (make that 5 LONG days at a conference) this was a total treat.
Bathroom: The shower was pretty big and I like that it was separate from the sinks. Products were great - some brand, Prickly Pear (?).
Gym: I really wanted to go...it looked very clean, small, but had a lot of equipment.
I took a star off because the resort fee does suck - especially since I didn't get to use any of the amenities.
