Alex,
I have relatives in the Woodlands and I just visited them last week. I flew into David Wayne Hooks (KDWH) and found it convenient. It’s under Houston’s Class B, but it has a tower, so departure clearances are not a big problem.
DWH has a few non-precision approaches, but no ILS.
I parked at the FBO run by the airport. There is a big “piston airplane” parking lot between the ramp and the taxiway. Self serve fuel was $2.40/gal. Since I bought fuel, they did not charge me for overnight parking. The FBO has nice facilities, and the people were very pleasant.
It’s a 15 - 20 minute drive from the airport to the Woodlands, depending on traffic.
I’m going back on Saturday, and I will use DWH again.
