Disney Resort Line

I'm heading to Disneyland and Disneysea early Janurary, just got a few questions I hope someone can help me with :)

1. I am planning on getting a Skyliner + 3 day unlimited Tokyo Metro pass, can I use that unlimited Tokyo Metro pass on the Disney Resort Line or do I need to get a separate ticket?

2. I will be traveling with a 4 year old. Apparently children under 6 years old traveling with a paying adult can ride for free. Does this apply to the Disney Resort Line? Or will he need a ticket?

Thanks in advance!

As its name implies, the Tokyo Metro Pass is only valid on Tokyo Metro lines. The Disney Resort line is not a Tokyo Metro line.

Up to two children under 6 travel free with a paying adult. Everything is here:

1. You need to buy tickets. TDR Line is a different company from Tokyo Metro. IC cards such as SUICA, PASMO are available.
2. Your child does not need a train ticket. It is a common rule in Japan, except a seat reservation.
Have fun!
