We were at the Westin Starwood Resort in Mammoth Lakes, CA and the charger was reportedly free but they charged us $20 for Valet parking for one hour. We begrudgingly charged as we had no choice but they lost our business as we refused to eat at their restaurant where we would have easily spent $60. I hope Tesla gets a Supercharger in Lee Vining soon as on our 3000 mile round trip from Los Angeles to Seattle the only time we paid for a charge was in Mammoth Lakes as we couldn't make it from Reno to Bishop, down the SR-395 in the rain without a stop. Otherwise the trip was flawless. Tesla is the best road trip car ever! We used the destination chargers five times for free on the trip, twice at the Seattle Tesla Service Center, at a bank in Minden, CA, at a Rabobank, and at a resort in Bend Oregon all for free. We ate at the restaurant at the resort in Bend Oregon. It was beautiful there.
