|Subject: Re: Mexico Advice from Ziners..|
I would rent a car. There is no train service. Bus service is great in this country, with a degree of comfort that we don't know in the US. But the drive to Acapulco on the toll highway is easy. The drive up the coast is not on a toll highway and will be slower.
An option to consider is to drive through Morelia and spent the night in Patzcuaro. then drive the next day to Ixtapa. Also, I would look into staying in Zihuatanejo, which is right next to Ixtapa. These things are a matter of taste, but we much prefer Zihua. It has some spectacular hotels, including La Casa Que Canta.
