We sleep in beds with no guarantee that pillowcases are actual sanitized, showers that may not be completely sanitized, sinks, counter tops, table tops, forks, knives, etc.
Before I use a glass or mug, no matter the accommodation, I thoroughly wash it and like everything else I come in contact with, I hope it’s clean enough to use.
I hope housekeeping, anywhere I ever stay, is thorough, whether it’s a Marriott or a DVC, Hilton, etc.
I do know Marriott’s have a more complete kitchen supply than I’ve ever seen in a Disney villa. Hopefully they don’t replace their steak knives with plastic anytime soon!
