I'm bracing myself for a rather long trip: a 3 hour flight, 8 hour layover, and then a 16 hour flight.  Also, I will be getting up around 4am that morning.  So it will be really helpful if I can find a place to take a nap.

[This question](http://travel.stackexchange.com/questions/4720/where-to-nap-in-chicago-ohare) contains some information about AA Admirals club.  However, since I'm travelling with the United Airlines, I am thinking about purchasing a one-day-pass for the United Club (Terminal 1).  Will I be able to take a decent nap in the United Club?
