Planning Rv road trip from Va to Gettysburg then Niagara Falls then Corning then Hershey then Philadelphia and back to VA very end of March/beginning April. How will roads be with weather driving RV? Any roads to avoid? Traveling with kids (9 & 12)and 2 dogs. Where to stay in Gettysburg, Niagara and Hershey? What to see, do, eat? I know it will be cold and possibly snow and that some places are closed, that's why I'm looking for help!
