I have been comped lots of dinners, high end scotches, show tickets and fight tickets. Of course, they were all "earned" as a result of my play. However, the coolest comp I ever got was when my boss's family of four were going to Vegas (I was not going). My Mandalay Bay host arranged for four tickets to Ka and four tickets to the Lion King for them, at my request. I was extremely impressed since the comps were given even though I was not on that trip. I am sure that a lot of the high rollers on the site have much more impressive comps, but that one is my personal favorite.
