I've got a 1 week permit I could just hand to the driver, but the booths are almost never manned before 8am. Was going to do a hike deeeep into Wild Basin, which is an amazing part of the park, but Lyft says it doesn't serve the area, and Uber isn't pulling up a single driver or allowing me to schedule a ride in advance. Surprised in this resort town there aren't lots of people driving for Uber on the side - I thought the early time might be a problem but not a complete lack of drivers.
