I usually place $25 on the pass line. When I'm uncertain about the table usually place 2-3 $10 come bets and take odds. I usually end up placing at least $30 each on 6 and 8 (sometimes other numbers as well) and press up my bets.
So my average can be pretty low when it sevens out quickly and can easily get up there into the $100-200 range when I actually get my numbers to hit a couple of times.
Last time I stayed at TI, my luck was so bad that I think they rated me as having played only 20 something hours at about $80 average over the course of 4 nights. But because I had changed thousands of dollars they gave me FRB. I didn't really eat that expensive though. I think they comped me about $400 worth of food?
Anyhow, despite having played a lot at MGM properties lately, when I called up Casino Marketing at Bellagio, they gave me nothing. Not even a discount. Mirage gave me only the promotion rates they sent me and everyone else. I didn't call TI since I've been unlucky there, but last time they comped me two nights up front.
Anyhow, I am planning a 5 night trip in March. I would love to stay at the Wynn this time, but it's going to be tough if I lose money again and have to pay their regular rates. Venetian is going to be less. While Mirage will certainly be the cheapest (although I would strongly consider getting a suite at the Mirage if I can easily get it comped). Sorry for the long winded answer. I do go to Vegas often and it's worth it for me to spend the time and money to build up loyalty (if it exists). Venetian/Palazzo does seem to send out promotions often, while I heard Wynn sends out very little regardless of how many times you stay there.
