I thought it was the end of the year, but the 50th celebration ends in the fall, so I don't know!?!?!?
In my completely personal opinion, I think the FREE ME will end with the 50th. I am guessing (really guessing!) that they will have a slight charge for it, still way below Mears and limo prices to keep it desirable. I'm thinking it will be "included" in packages, and a small charge for room only reservations.
If we were going in December again, I'd call and reserve now. They'd have to tell you if they were going to charge you for DME service.
