I have a flight coming up on March 31st. I’ll travel with my 4yr old & 4 month old. We all have US passports. I have some few questions:

1. We’ll fly from Boston to Narita Airport and then have to transfer to Haneda for our long layover. Will they transfer our luggage to Haneda?
2. How do we go to Haneda in a not so expensive way?
3. Where can “sleep” in the airport with not having to pay for hotels or so on?
4. Any ideas where to go and eat around Haneda airport that’s good with kids?

We’ll be in Japan by around past 4pm. Please share some ideas how you guys manage to travel with kids. I’ll be just with myself and with my kids going to the Philippines
