Late departure in Narita

Hi!

My family's flight departs Narita at 6:30 pm. We're checking out of our hotel in Kinshicho at 11 am.

What are some options for our family (kids ages 10 and 11) to do? Do we hold our luggage in the hotel and explore for one last time?

What time should we start heading out to thee airport?
