How to TR offers work for someone who has a pretty low level of play/history? Do they throw offers at me until I take one? Or will they keep sending me the same offers unrelated to which ones I've used, as long as my theoretical loss level stays in the same range?

I've got a comped room (3 nights) offer for Vegas that I could use this month, but I would probably get more value out of something similar later in the year. Should I just go ahead and use it and hope that something similar will be available to me later? Or save it for a time when it will do me more good? (The earlier trip I'm fine to stay in a cheap room somewhere, but the later trip would be more important to be at a nicer property)

I don't have any TR status, but I played some high-limit video poker last year in an aborted attempt to make Diamond-in-a-Day, which is I assume why they are now sending me low-level comp offers.

thanks for any guidance...
