Sitting in IAH with 7 hours between MEX-IAH flight and my EJ connection home. My wife and I would pay for a secure pod each if they had such. I would love to have such places (not the full disrobed style pod hotel as in Japan, but similar for fully clothed travellers) to catch a secure nap with a very strong built in alarm that goes off 5 minutes before the amount of time for which you have paid ends. I worry everytime I get up in this very crowded RJ terminal that someone will lift something while my wife is dozing. It would likely not happen but then again most crime is unlikely but when it happens to you it huge.
Also, today I would be worried of being the next social media unwitting star - I can just see some of the folk I am watching taking pics of a drooling old guy or gal and putting such up on facebook!
