Doug and Carrie both have very specific ideas on how to spend their vacation together. Doug wants to rent an RV, while Carrie prefers a visit to Paris. They flip a coin, and Doug wins. In order to make Doug reconsider his idea, Carrie invites her father on the cross-country trip. She assumes that Doug would not want to spend his vacation in a confined space with the old man. However, to spite her, Doug not only agrees to take Arthur along, but invites Spence as well.
