Traveling from Habuka to Narita Airport

In February, 3 families will be traveling from Seattle to Tokyo (for a few days) then to Habuka Valley to ski. What is the best way to get from Habuka Valley to Narita Airport? Bus/Train or Private Car? I think we will do the bullet train to bus to get to Habuka just need help with how to get back to the airport.
Thank you.

How to get to/from Hakuba to Tokyo is explained here.

There isn�ft really a reason why you would choose a different route back to Tokyo/Narita

You mention families. So I guess you have children also travelling.

Any bus option would be a no-no for me. Trains just allow you to get up and move if needed.

Train to Tokyo. Transfer. Train to Matsumoto. Transfer. Train to Hakuba.
