The restrooms in terminal E are the best in this airport. The restrooms in terminal C are smaller and the toilets don't flush well at all. Avoid the restrooms in terminal B they are tiny and suck.
Allow significant extra time for connections that involve using the tram. Missed my flight because it was broken for 40 minutes while they "looked for a piece of string" to fix it. I'm not kidding.
Fly through Hobby Airport when coming to Houston. This airport is poorly laid out and very inefficient. Takes forever to get to the rental car facility.
Never stay @ the Howard Johnson . Advertises free shuttle but fails to note only before 10 am or after 5pm. Clerk rude & refused to get manager to resolve issue.
George Bush Intercontinental Airport is the 8th busiest airport in the U.S. and offers service to more Mexican destinations than any other airport in the nation.
