$20 Trick in AC Anyone?

[FISHCAKES]

Lately I have been really blessed and have been getting my rooms at the Borgata comped. I guess I should be grateful because the standard rooms are quite nice but I don't qualify for an upgrade to a suite. Im going down with my girl this trip and I was wondering if anyone has had any success using the $20 trick at the Borgata, or for what it's worth any other AC casinos?
