I've never heard of any JR Pass discount though.

Hi there,

While the above linked route is covered by the JR Pass Maihama - Shinagawa stations. You may still have to use the Disney Monorail to Maihama station. This is unfortunately not covered.

The route looks like this see route#2 or route#3.

We have the 7-day 1st Class JR Pass? Will we be able to to it?

From Maihama - Shinagawa...Yes! The Disney Monorail is not covered.
