For PAX Unplugged my group would take the train from Boston to Philly. It’s the best. If your wallet can take it (the price points are weirdly high, and absurdly high compared to the Bargain Busses that occasionally catch fire) but for that you get legroom, a smooth ride, room to set up your laptop, and (pre-covid, at least) a snack car.

For PAX we’d set up in the snack car and play board games the whole way down. Can’t do that on a bus.
