My family (parents + sibling) will be heading to Tokyo this 6th - 10th.
Didn't give too much planning since they wanted a casual walk, eat and shop trip.
Hotel is near Shinjuku Station and will be flying there with ANA.
With that in mind, my rough itinerary is as below. Kind feedback is appreciated.

Feel free to advise anything, especially what to do at night. (But I suspect my parents wanna go back hotel and rest

)
RegentCid, got a few things need to confirm on NEX.
1) For NEX I know train ticket reservation is a must. I'm buying that 4k JPY ticket combo, am I required to reserve my return ticket when I buy at Narita? Or I can go JR counter to reserve when I going back? (I want to reserve at Tokyo station to NRT)
2) When NEX train go to Tokyo, need to change train carriage? I'm going to Shinjuku but I see NEX train depart to two different terminal location from Tokyo station.
Thanks for clarification.
I think you should spend more time in kawagoe and going to akiiharaba is quite far. I remember we took the train from the station where the kit kat museum and it was far from akiharaba
