Hi. I’m researching our family trip summer 2020. We’re going to go Seattle to Chicago, getting off at Glacier NO for a few days, then getting back on and completing the journey. Starting in Seattle, getting off at west glacier, getting back on at East glacier, then ending in Chicago. We are a family of 6. 2 adults and 4 kids (2-10yo). Is there a way to book multiple rooms online or do you have to call? Can you book 4 in a family suite then two seats and trade off? How would you recommend we book? We are wanting sleeper rooms.
