I am over the whole Amish experience, but still love Sight & Sound Theater and anywhere OUTSIDE of those tourist trap areas.
Last time we travelled that way, we stayed at
STARLIGHT CAMPING RESORTIt is roughly half way between Hersey and Sight & Sound. A quick drive, and we watched NOAH, ate with strangers, then drove back to peace and quiet.
Another day...quick drive and I learned all about Miltom Hersey, and got my Master's in Chocolate Tasting.
If you are going to do the WHOLE TOURIST TRAP THINGY....this would not work for you. Might as well stay at Old Mill Stream, or one of the others suggested. That way you can ride the train, see a show, tour on a buggy, etc...
Personally....if you want to se Amish, leave Lancaster. Or better yet, come to Western PA/Eastern Ohio. All kind of Amish in their natural Habitat (that sounds awful, put that way).
