With six spacecraft currently docked at the ISS, how could Santa (or anyone else) deliver presents?

Considering how all the usual docking/berthing ports at the station are occupied, Santa would likely arrive in a Dragon Crew/V2 or a Boeing CST-100 vehicle. These are the next US vehicles that will be ...

With six spacecraft currently docked at the ISS, how could Santa (or anyone else) deliver presents?

Look at Santa's sleigh. See anything resembling a docking collar? No?--then why do you think he has any use for a docking port?? It's obvious he gets there via EVA. The ISS airlocks aren't blocked....
