We're looking to take the train from Stamford, CT to Washington Union Station on a Friday morning (10am). Do we need to transfer at Penn Station or can we stay in our seats? My plan was to reserve seats in business class so four of us can sit together (2 adults, 2 kids). It would be unfortunate if we had to transfer and then try to find four together on a different train. I was planning to get coach on the way back Sunday afternoon, thinking it would be easier to get four together since we'll be at the origin. Is this a reasonable assumption?
