I think there's a wee issue with
breakfast room service, but otherwise, at least in a city like New York where food delivery is omnipresent, it really isn't a necessary service. Having some sort of 24 hour counter in big hotels where people can grab drinks and snacks really would be a perfectly fine substitute. Room service food mostly sucks as for some reason they focus on just serving up "normal" food rather than food that can handle a lag
team time between preparation and consumption. Food meant to be served hot generally sucks when it arrives cold.
Just partner with local delivery businesses.
