7 Day JRPass good for my itinerary?

Arrive Thursday evening 11/19 Narita Airport at 4:30pm
Fri 11/20 Spend day at DisneySeas
Sat 11/21 Spend Day exploring Tokyo
Sun 11/22 Travel from Tokyo to Hakone (via Odawara station)stay overnight
Mon 11/23 Depart Hakone to Kyoto (stay overnight in Osaka)
Tue 11/24 Explore Koyto (stay in Osaka)
Wed 11/25 Explore NARA and return to Tokyo (stay overnight Tokyo)
Thur 11/26 Tokyo in a.m. depart Narita airport at 6pm.

Questions: Does a 7-day pass make sense?
if so, when should I activate 7-day pass?
Any feedback on itinerary would be welcome.

Thank you.
