Finally registered just to reply to this one--

I did an event at a Sheraton in 2009. They provided us with a mug that was good for unlimited refills of any beverage, any time, at any of the hotel dining facilities. Drank more than my fair share of Fat Tire in that! I still use the mug (it's a travel tumbler in a red-toned ombre with the Sheraton logo and name of the city on it) all the time. I know that's unlikely for a hotel to offer to everybody staying there -- we were doing a convention -- but it was very nice and I do still use it!
