Yea... I like the concept. But, from the rental car facility? The signage going north, over to Will Clayton is actually quite confusing. I drive there all the time, and I sometimes get screwed up going that way... end up circling a terminal. :-(
It's a pretty straight shot on JFK to B-8 (left exit flyover) then to I-59 South. (also a direct exit ramp). Not sure how it could be any easier. ??
I'm a local so only deal with the parking lots, not familiar with the rental facilities' locations so may not be qualified to give directions from that perspective.
logitech,
Post Oak and South Post Oak are two different roads, the link I put in my first reply was to Post Oak. South Post Oak is on the southwest corner of Loop 610 and goes south from there.
