Just got back from the Austin City Limits Music Festival. Stayed at a campground in Downtown Austin near Zilker park. Minimum 5 nights, $100 per night. It was a 12 minute walk to the Festival entrance.
The next closest was about 7 miles away, $30 or $35 per night, if I remember correctly, but almost an hour commute during rush hour and $30 to park near the festival entrance.
My daughter went last year, stayed in a Motel 6, about 4 miles away, and the 3 nights she stayed cost as much as our spot rental for 5 nights. Plus she either had to drive in or take a taxi.
Yes it was spendy, but in the wear and tear vs aggravation, not a bad trade off.
But it'll be a few years before I do it again. LOL
