I'm just not convinced they're going to do anything to EMH. I think this is another way of monetizing their off property guests. But EMH is one of their big selling points for getting people into their on property resorts, and that is a HUGE priority for them. Plus, the survey they just recently sent out floating the idea of a resort fee -- which I think we all know is coming -- specifically said one of the perks paid for by that fee will be EMH.
I tend to think they will leave the EMH as they are, and just monetize them a bit through the resort fee, and then they will have this separate after hours experience as a way of getting off property guests to pay for the same experience.
