We have 3 full size luggage with 2 young kids and will be stay at Sunroute Plaza.
We were considering taking the NEX and arriving at Shinjuku station as the journey is shorter than limousine bus.
But reading from the forum, seem that there is only a single escalator going up or down at different time of the day and there is also a new exit to reach Sunroute plaza .
Due to the heavy luggage, we try to gather all the route without pushing it around and get lost in the station.
Can anyone visiting the station guide us on the direction?
