I took the bus with my friend from Toronto to Washington . The ride was 14 hours and we made it there when we were promised the bus didn't run late , it doesn't matter when you are traveling summer or winter the bus AC is blasting on high it's freezing on the inside but if you have a blanket you should be fine , the wifi does not work properly and you can't stream on it !
Thank god for plugs to charge your devices cause otherwise you be so bored they do not show a movie or anything on the bus so make sure to bring entertainment with your selfs . Other wise it's a very affordable way to travel .
