When in November 2018 will you come?
Please note that the 23rd of November is a public holiday, not a weekday.
Are you expected to use Terminal 1 of NRT?
Train timetables for Narita and Haneda Airport accesses
may be revised in October.
May I ask which will be the preferred station to transfer at Compared to Aoto Station,
at (Keisei) Takasago Station,
the two tracks beside the platform are closer to each other.
The difference in levels between the train car's floor and the platform
may be large.
Please watch your step when you change trains.
the 4.04pm direct Keisei Access Express (which is the last direct connection from Narita to Asakusa for the day). That is not the last direct train for Asakusa.
Currently on weekdays
the 18:02 | 18:53 Limited Express train is scheduled
to go on Keisei Main Line until Aoto and Keisei Oshiage Line until Oshiage
then become a Toei Subway Local train to go on Asakusa Line,
which makes a stop at Asakusa Station.
At the Keisei station in NRT Terminal 1 or 2:
To catch Keisei Limited Express trains,
you pass through both the entrance and intermediate gates;
To catch Keisei Access Express trains,
you pass through only the entrance gate.
Access Express trains
go by Narita Sky Access Line until (Keisei) Takasago.
considering it might be peak hour by the time I reach these stations (around 6pm) I guess Keisei trains for Oshiage are not quite crowded in the weekday evening.
(During the weekday morning commuters' rush, they may be packed with passengers.)
I know there's Keisei Skyliner that will bring me to Ueno, but then I will have to walk quite a bit to the main Ueno station The underground pathway which connects
Keisei Ueno Station's outer concourse
and subway Ueno Station's Ginza Line outer concourse
is fully equipped by elevators.
It is about 5 minutes just to walk through the pathway,
maybe plus some minutes to wait for elevators.
Subway Ginza Line was opened around 1930;
even now, train cars are relativity small,
and there are stations which have two platforms
completely separately
or connected by only a pathway which has stairs.
Anyway, it is strongly recommended that you pack lightly.
