Maybe the Platinum card helped.
I would imagine it's a function of US liquor laws. Luxury hotels likely get a good number more 18-20 year olds traveling alone versus under 18s.
I've never heard of it being an issue or someone being denied check-in, but I can think that the worst that would happen is that the hotel would want to simply clear the booze out of the minibar. Having a good form of payment is really all I can imagine them caring about otherwise.
