Lin,
What you're saying can very well be true because there are casinos that do actually factor in whether you have done well on your trip(s) as to what they may offer you!
I (at least previously) was told that they do take that into consideration at Plaza and Las Vegas Club and so it certainly could be that way as well at El Cortez (since they were all previously owned by the same people).
