I keep seeing threads where people are asking for transportation from the Palm Springs airport to Coachella.
There is a bus that runs right from the airport into Indio, it drops you off at the In and Out burger which is about 3 miles from the festival grounds.
IT COSTS A DOLLAR!
It runs like all day long. From about 5am to 10ish or something and it runs 7 days a week.
route number 111.
I took it last year and while its probably slower than taking a cab, it costs only one dollar!
Seriously, dont waste your money on cabs (costs about 100 bucks) or rental cars, take the bus then buy yourself an extra shirt with all the money you'll save
