So my brother (aka cameraman) is meeting up with me for an upcoming hunt. Only a 3 hour layover going, but on his way back he gets in at about midnight and then flight leaves at 7am. Any suggestions on what he should do to kill 5 hours or so? Maybe get a little nap and a shower?

If he is travelling on Emirates, Business or First Class, there are showers and very comfortable lounges at Dubai airport.
