Bus or train to Ginza station from Narita

We will be arriving at Narita at 6pm on a Friday night, then heading to our hotel near Ginza Station. I am considering taking the Access Narita bus, which would take me to the station. Has anyone used this service? Would there be a problem with traffic on a Friday night? Or do you think it would be better to take the Narita Express to Tokyo Station then take a taxi to the hotel? Thank you for your help.

At the Keisei Ry's Narita station some trains run into the Asakusa subway and go to Higashi Ginza. There is an underground passage to Ginza station.
Do you have the address near Ginza station? I can send you a map showing where it is.

We are staying at the Millennium Mitsui Garden Hotel Tokyo
5-11-1 Ginza, Chuo-ku. Thanks for your help!

Depends if you like trains or buses more. I prefer the trains (less traffic, more room), but other people like the bus.

Here are two maps of the Ginza area showing your hotel. It looks like there is a direct connection into the hotel from the Asakusa subway.
At Narita the station attendant can tell you what time the train leaves. Be sure to tell him HIGASHI GINZA. The trains have an airplane in the sign as you can see in this photo.

In the large area map you can see there are 4 subways you can reach underground.

In addition to the trains with the airplane in the sign, trains signed NISHI MAGOME also run through the Asakusa subway.
The trains are the most reliable and fastest way for you.

Thank you so much for your most helpful advice. Much appreciated!
