I suggest ending your ride in San Luis Obispo. There's a great hostel a block from the amtrak station, and numerous bike shops in town to box up your bike to ship home (I recommend Foothill Cyclery). After taking care of business, you can jump on the amtrak for the bright lights of Southern California where you can be a tourist before flying back home. To me, this plan requires very little effort on your part to succeed. Good Luck!!
