There is parking at the location. You will have to walk from the parking to the ceremony location but it is a very short walk. The grandparents will park up front by the barn.
If your invitation says “and Guest,” then yes, if not, we would prefer if it was just you.
There are two roads that are easy to miss that you have to turn down. We will have signs out saying that you should turn here and if you pass it there will be a sign saying you missed it. We have gone there twice and both times Nick missed the road.
