It's a waste of time and resources for hotels to have me stay for ten hours during a layover. They'll need to wash the sheets, vacuum the room, and clean out the bathroom for my six-hour nap. The airport is too uncomfortable but the hotel is overkill. Pods would be a nice in-between for <12-hour stays. I wouldn't even mind if the pods were in the hotel because then I get to passively benefit from the hotel's security precautions.
