I will say, if you don't wish to drive while you're here, you may want to look for a bus tour. Public transportation outside of metropolitan areas is sketchy at best and in most places, completely non-existent. Amish country is beautiful, and there are lots of tour bus companies that have travel packages. I can't speak for any quilt-specific ones, but considering that's a huge part of the Amish appeal, I'm sure there are some out there.
I grew up playing with the Amish kids when my grandpa would go visiting. They're a wonderful group of people, and I find them inspiring and refreshing.
