Re: Convention contracts
I don't work for MGM or any hotel, but I have been involved with conferences, and any good event planner would have this in a contract. So I'm betting @cirby is correct. When we sold out hotels we had language that prevented companies not exhibiting with us from booking a suite and setting up their own off-floor demos, which drives attendees away from the exhibit floor and from the companies that paid.
If IGEL bought a booth and went through VMWare they probably could have had their lunch.
Restaurant managers are not privy to the details of contracts, or to the intricacies of the IT industry, and so may be excused for not knowing this could be a problem.
