There are four different airports you can fly into to get to Pátzcuaro.  
We recommend flying to Morelia (1.5 hours from Pátzcuaro), where we
can meet you outside of customs and take you to the hotel.

Continental Airlines has flights through Houston to Morelia that land at
approximately 7:56pm and depart at 6:30am on the return trip.
Cheaper flights can be made via
Ixtapa/Zihuantanejo (ZIH), which is about
a 4-4.5 hour drive from Pátzcuaro.  The
cost of the retreat does not include
transportation to or from ZIH, but if you fly
that way (or even just one-way), you can
spend an extra day or two at
the beach

Michelle can help you rent a car (and/or a
van if there are a large number of
people); help you figure out bus
schedules; and/or give you
recommendations for places to stay at the
beach.
