Honest question, but do they have any system for counting drinks at the resort? Or do they just cut people off when it's clear they've had enough?
I think they wait just a little past the point when it's clear they've had enough to cut them off. I've seen people nearly to the point of passing out, people who couldn't even walk and people who had no idea who or where they were.
To clarify the above, I'm a former Disney server and bartender and can confirm there is no 'counting' of drinks or official system like that. Anyone who serves alcohol is required to take classes on recognising the signs of intoxication and once a guest shows these
early signs, you are, according to Disney standards supposed to cut them off. Too often, CMs wait too late to cut people off as they don't want to sacrifice their tip or deal with the verbal abuse.
Let's face it, bartenders are working for tips and if you aren't willing to serve them, they will find someone else at Epcot or wherever who will (and the refuser will lose their tip, if applicable). At least this can't happen at MK - people won't be able to buy drinks for the refused guests either. Personally, I will always cut someone off once that early line has been crossed as I've been
that drunk person and witnessed poor behaviour from others with serious consequences - I cannot say the same for all Disney bartenders though! Totally down to individual morals.
In terms of alcohol, Magic Bands won't ever be used for anything other than the actual payment (unless something drastic changes). Everyone's 'level' is different and affected by alcohol differently - you need someone to subjectively assess each situation/guest. Similarly, you can't use Magic Bands as a form of ID as it would violate state drinking laws.
