Only taking Bitcoin into account would be a shortcoming. You not only want your customers to use the convenient way of paying their stuff with bitcoin, you probably make them more focus on the value they get out of their bitcoin-spendings. So in fact, Bitcoin needs to disappear and the convenience consumption of goods and services at your hotel at the customer's fingertips needs to get into the focus.

Excuse the branding, but, as an inspiration, look at this experimental implementation of ordering beer at a beergarden and what that process would even make it more simple if things are paid with bitcoin:

Here is another example of the smart wineshelf (noy yet in video):

Bitcoin is not enough. Don't underestimate the effort of letting Bitcoin disappear, focus on the customer's value (getting out of his bitcoin spendings), and not even have a proof of concept, but having it as true working solution for your usecases.

good luck!
