I'm thinking:
Leg 1: Los Angeles, California to Valparaiso, Chile
Leg 2: Valparaiso, Chile to Puerto Varas, Chile
Leg 3: Puerto Varas, Chile to Bariloche, Argentina
Leg 4: Bariloche, Argentina to Liverpool, England and possibly Germany?
Leg 5: England/Germany to somewhere in France (rural)
Leg 6: somewhere in France to Lilles, France
Leg 7: Lilles, France to Seychelles
Leg 8: Seychelles to Kuala Lumpur, Malaysia
Leg 9: KL, Malaysia to Penang, Malaysia
Leg 10: Penang, Malaysia to Singapore City, Singapore
Leg 11: Singapore, Singapore to Shanghai, China
Leg 12: Shanghai, China to San Francisco, California
