Thanks RVGRINGO for the route information.As you approach Guadalajara, watch for the large green signs for 'Mexico' or 'Aeropuerto'; favoring the one for 'Mexico' as you go along. It will put you on the outer loop (periferico), and then put you back on the toll road (cuota) toward Mexico City. Then, watch for the signs for Lagos de Moreno and you'll get there without difficulty.
