HIMYM: Should Lily Aldrin and Marshall Eriksen move to Long Island or stay in the city?

In How I Met Your Mother, Lily Aldrin and Marshall Eriksen were recently given a house on Long Island by Lily's grandparents. This forced them into making a decision between selling the house or moving into it. Initially, they decide to sell it. They visit the house, and are overwhelmed by its size. However, they still decide to sell it.

When they get back to their apartment, they realize how small it is and how cramped they are living. After seeing how large and how much space they would have in the house in comparison to their apartment, they decide they want to move into the house.

Robin Scherbatsky, however, does not want them to move and begs them to stay. What should Lily and Marshall Do?
