Your wife will do well when the water wars start and you’d be wise to start following her lead.

As as aside, next time you know you’re going to a hotel bring a secret, second ice bucket to fill shortly after she fills the hotel one. Bonus points if you can acquire it from the hotel so they’re identical.

Don’t mention it or anything, just let her work out the logistics of what happened when she notices. If she’s as serious about hotel ice as she sounds, you’ll probably get laid right then and there.
