Hi We're looking at a group of about 18 taking a trip on the Empire Builder from Milwaukee, WI to Whitefish, MT next August. We're looking at the Saver option. If we want to be able to stay somewhat together do we have to book as one or is the seating general and we can all book on our own (frankly, I don't have the cash to cover everyone)? When I was perusing Amtrak's site for booking, I entered 6 guests and under the Saver it stated "1 reserved coach seat". What does that mean? That seating is as available but we'll have one seat reserved? With regard to traveling on the Empire Builder, is upper or lower generally preferred? How are dining and drinks handled and are they reasonably priced? Can you bring your own food and drink on board? If yes, what about alcohol? Thanks much for the education.
