Tokyo Haneda Airport Limousine Bus

[ZaraW]

It's my first time travelling into Haneda Airport usually we land in Narita.

Can I buy a return ticket to Tokyo station? I looked on the website but it only mentions a single ticket. If I can't get a return is there a ticket machine at the bus stop or I can buy one from the driver? I don't want to take the monorail and subway as I'll be arriving at a peak time.

TIA

I used this last year, and it was very easy to get a ticket from the machine at Tokyo station

Thanks that's good to know.
