Depends where you play. Places in LA like Commerce, Hustler, and the Bike give you $1 an hour to play. I live locally, and dont stay in these hotels, but you can use the points towards food service, their gift shops, etc.
In Vegas, all the Total Rewards properties (Ballys, Mirage, Rio, Harrahs, etc) give you $1 an hour as well. Aria (M-Life) gives their players $2 an hour.
If you play a lot, the points will add up fast, and you will start to get comps in the mail. I get emails from Total Rewards all the time. I believe i get 2 free nights a month. You do have to pay the resort fees ... but you can use your points to pay for these.
The only thing i need to mention is that just like with the CardsChat Freeroll Club ... there are no shortcuts. The more you play, the better your comps will be. And if you start to get offers like i get, but you DONT go back to Vegas for a year ... your comps are going to go bye bye. So show some dedication, play a LOT, and have fun !!
