I found this for those who want to learn Spanish in Morelia.
"Study Spanish while touring a most magnificent country! Lessons will be given while visiting several important and diverse places in Central Mexico.Our classroom on wheels is available for groups of 10 maximum. This tour is appropriate for students of all levels." It lasts 8 days and it has an interesting itinerary. Their info is in www.mmg.com.mx They call it Spanish Lessons on Wheels ans they start in Morelia.
