Laguna Beach ? You mean John Wayne in Orange county right ? Usually it's at least $100 more than LAX to fly into/out of..... but OK.Cheapest is the Motel 6 in Mammoth .There is a shuttle from Mammoth's airport to the mountain.Free bus rides around town.If you could afford it Mammoth Mountain INN is right by the main lodge and is the closest to the lifts.I believe lodging will run you about $100 and up a night.Try goggling "Mammoth lakes motels/lodging" ...you might find something cheaper.
Man that is 1 good buddy of yours...make sure you tell him THX for the rides.[and buy him some gas too ]
