Post HTX is in downtown Houston in the Theater District. Of the city’s two major airports, Hobby Airport is a bit closer at about 12 miles from the venue. Rather than deal with downtown traffic yourself, your best bet is to call a ride share.
The organizers recommend you stay in a hotel downtown. Makes sense. Depending on where you stay, you may be able to walk to the venue.
Well, you don’t really have a choice here because everything is from Texas. That’s a good thing. Texas rules, and you’ll love everything it has to offer at the festival.
