I know comps are pretty sporadic, but this doesn't make sense at all.
I gamble once every month or two, pretty much all blackjack and craps. Have been to Vegas 3 times in the past year and a half, always use my card. This past time I got the TR credit card also so got upgraded to Platinum. I only have like 800 Rewards Credits so don't gamble a ton, but never ever get any free room or comp offers, and the rates are hardly discounted at all from normal rates even during the week at the lower end casinos (Harrahs, Flamingo, etc.)
My brother has gambled twice, once in Council Bluffs Harrahs where he signed up for the card. Probably lost $100 there, then a few months later when we went to Vegas, where he won around $1,500 on the trip (roughly the same as I did). He only has 78 reward credits at this point. Again he plays only BJ and Craps. He checked his offers today and has all kinds of free room and comp offers. He can stay at any of the lower end casinos from Sunday-Thursday for free through December for most weeks, and if its not free the rates are like $25/night. Even weekend rates are $100 or so for PH, and Paris. This just doesn't make any sense to me, anyone know why we would have such different comps when I gamble a lot more?
