If MGM is $20, the differentiator of $10 would keep them going a long time. No need to be 'free', just 'cheapest parking in Vegas'

The MBA's they hire would not be able to do that. If they are making $1M from parking fees at half the rate, then surely they can make $2M by doubling the rate and no harm since everyone else is doing it! I hope the local casinos don't follow suit but given the history of the resort fee they will be right on the footsteps of the strip casinos.
