So we drove to Niagra Falls and then headed for Palmyra New York. As we prepared for this trip I tried looking up info of things to do and places to stay along the drive and length of driving and didn't ever really find anything helpful. Hopefully, if you are planning a trip like this then some of this will help you.
When you leave the American Side of Niagra Falls prepare for about 2 hours in the car. Be sure to stop in Pittsford, New York. It is right on the way to Palmyra (about 20 minutes to go) and you will be in store for a heavenly reward. Stop at the Pittsford Dairy on main street. They have amazing sweets and homemade icecream (and it really does taste better if that was possible) and get some chocolate milk.
There is a candy store about 3 shops down but it closes around 5. We were disappointed in that. The Grandin Building stays open until 7 so you could go eat before if you needed a break. We ended up walking down the road to Nima's Pizza and ordered a whole pizza. During the 20 minutes wait we walked up the street about a block and on your right hand side there is a fun park set of the main road. It kept us all happily entered so we weren't drooling over upcoming pizza.
