Missing his extended family, Rob thought of having the McCallisters come to France, eventually deciding for them to visit during the Christmas season. He then paid for the whole McCallister family's trip to Paris so they could all be together for the holiday. However, Rob's nephew, Kevin was accidentally left home alone and Peter and the rest of the McCallisters went to Rob's penthouse apartment while Kate tried to get a flight home to Kevin.
During his extended family's stay, Rob and his wife Georgette decorated a Christmas tree with their son Steffan assisting them while the other McCallisters watch a French dub of "It's a Wonderful Life". Georgette later calls out Frank McCallister for serving a shrimp appetizer, saying that they were to be served later.
A year later, Rob still owned a home in New York, which was then in the process of renovation. Kevin, after accidentally being taken to New York, used the house as a base of operations while defending himself against the Sticky Bandits.
- In a deleted scene Rob and Georgette and their kids were to have a larger scene at the airport where they made a "Welcome" sign to welcome the rest of the McCallisters. However, the family runs past them and into their sign ruining it, as they rush to get to the phones in order to make a call to Chicago, leaving Rob, Georgette, and their kids in complete shock.
- As his name is Rob, it could be implied that it was his nickname and his legal birthname is "Robert" or "Robin".
