I though it was going to be a real service - and one I'd dearly pay for (since I often run 18+ days with meetings stacked end to end and cross timezones). However trying to sleep in public on something like a coach class airline seat is not an option - it's like trying to sleep in McDonalds. What these guys need to do is create a day room exchange - a sort of AirBnB by the half hour or maybe day rooms.
Hey, if I could get a napping desk (and be allowed to nap during the middle of the day) I would be all over that. As it stands, if I want a nap in the middle of the day, I would need to go to the car during lunch break, which isn't exactly that comfortable.
