JR East-South Hokkaido Pass

Hello

Just checking that the JR East-South Hokkaido Pass will include the following:

4 June Shin Chitose airport to Sapporo (this one seems to be an extra cost when I did a check)
5 June Sapporo to Hakodate
6 June Hakodate to Shin Hakodate to Nikko
9 June Nikko to Narita Aiport

Also, can we pre-book seats on all the trains?

Thank you.
