I find myself at the Palms quite often, though less frequently with every passing year. The movie theater and the salon are my biggest reasons to come, though I'll say that N9ne is one of my favorite restaurants and the valets will treat you like rock stars when you take care of them and they get to recognize you (tip them $5 when you drop off your car and they'll give you VIP priority when you are leaving, even if it's busy).
I'm not a fan of the clubs here; they all feel a little dated to me (and I'm in my 30's) and tend to be a bit obnoxious. Some of them do give a great panoramic view of the city though!
I'm also not a fan of how hard it can be to get a drink when gambling. We were here today for over an hour without a single waitress in sight and it was packed with heavy smokers. In the past I did most of my gambling here, but now the gambling is incidental and only happens when I'm there for another reason.
