I am considering booking a flight that has a long layover in Beijing Capital Airport.

The layover would be from 6:00am to 3pm. Is it possible to get a transit visa to go to hotel to rest? Where would I do that?

Do any of the hotels near the airport offer day-rooms that we could use for sleeping and showering? We are not considering staying in one of the hourly rooms located inside the airport as we've been told they often smell of tobacco smoke and I have one daughter allergic to tobacco. Thank you.
