[route advice Virginia to Niagra Falls]

yes, taking passports thanks for the tips. my main concern was not knowing what highways to travel. there will be a caravan of 4 class A rvs and a 42ft  5th wheel. I did google map it , time is not a huge concern but I got info elsewhere to avoid 219 which was on the google map route I got.  I also saw another recommendation to go out to I 90.   thanks so much
