I enjoy staying here when I come to Vegas to party and gamble during the Summer and I don't want to spend a lot of money on my room. They practically comp my rooms, even during peak times, and that's good enough for me.
I suggest arriving on Thursday to avoid the rush of people checking in on Friday and leaving on Sunday or Monday even.
The buffet is decent and so is room service. Slip the check-in clerk a 20 and ask for an upgrade and they can usually do something...although not always.
The lounges are fun and sometimes there's a rock concert in the Pearl (if there is one, you should highly consider seeing it because the acoustics in there are STELLAR!)
There's a movie theater on the property in case you get bored or just want to take a break from it all for an hour or two.
All in all - nice place, very clean, nice folks running the place and the bartenders are friendly. I recommend it.
