In recent years they've had a Coachella concierge service with house rentals, and transpo to/from the festival each day it's usually about a grand per person but it's VIP all the way. It's not cheap but this late in the game you're not going to find much cheap or convenient. In 99 I drove to/fro Palm Springs but been in Indio every year since, will second the horrible traffic situation at the end of each but when I see those poor souls walking in the dust for miles up the road each night I'm grateful to be inside SOMETHING rather than that. For future years you need to book in May/June the year before, most hotels will take reservations 330 days out, though all the indio digs are wise to coachella and juice you on the rate, the good years of 99, 01, 02, 03, and 04 are long gone since 05 the fangs have come out.
