Could you please answer a question for me please, on the eastern trains, we will be going from Philadelphia to Williamsburg Va. Is it possible to get pre assigned reserved seats? Is this available if you go business class? I think standard coach fare only gaurantee's you a seat a seat on the train but all seating if first come first serve. If you upgrade to business class, does that give a gauranteed seat? What other perks? Is it worth it? Also does anyone know the options from getting from/to train station in Williamsburg? Will a taxi be the only choice. Thank you
