I don't recall all of the amenities in Mt. Vernon or Millersburg, but they seem large enough to have lodging. Other than that, it seems reasonable to me. What changes did I make? I did it in 5 days instead of 6, but I ended up sleeping outside 1 night, which you probably don't want to do. And I don't blame you. If one were in a hurry, it could probably be done in 4.
