Covid-19 Vaccines and hotels

Hello, I am new to this forum. As a CEO to a company offering services to hotels related to health safety, I would like to collect opinions of hoteliers or people with similar role concerning the new developments with the vaccine. F+Do you believe it will solve uncertainty in a degree we will be able to return soon to prior business conditions? If so, how do you plane to handle vaccinated and un vaccinated guests within the hotel?
