Hey Meg
It was my first experience with Amtrak last July with children. DF paid for us 750 dollar with Deaf discount price. I brought Foods and Drinks Backpack with me to feed children. U can grab Micowave Foods like Chef Boyone (sp) cans and go to Lodge room. Attandent will heat it up for you. U can bring your own drinks and foods in train. I did bring 7 or 8 bags along with me. I know that is alot! Dining room is expensive food which Chef cook real foods and have seat table for you and kids. So better for you to bring Foods your own or Lodge room to buy foods like snack, pizza, hotdog, drink, breakfast foods, and Ramon. Alittle pricy of foods in Lodge.
Just give you an idea to save money to bring foods/drinks.
