Low-level gambler here. I dropped maybe $1K at Harrah's properties in about 6 months. I was killing time earlier and stumbled upon "my offers" in my TR account, and noticed some "special hotel deals."

Some dates were no dice, but I managed to get 3 free nights (Fri-Mon) at a Vegas property. I have a confirmation number, my e-mail confirms $0, and it looks legit. Is it really that easy to get comped rooms? Is Vegas doing that badly?
