@CPT, thanks for this info. I have often wondered if there was a way to do this, thought maybe could bring one in, leave and then come back with another, but I guess that won't fly. LOL If you're a 25k Diamond, I think $25 is worth is to bring a third person, but if you're having to pay for your own access, it would be a $50 hit to your comps. I would opt to have a decent meal elsewhere for that.
And, @BorgataBabe, that's really shocking that even though Zeus and Allen had their Gold and Platinum cards, you could not treat them with the comps. That seems a bit extreme to me. I guess they don't allow transfer of comps at the rewards desk either then???
