Getting around

   Hello!

1.We will have half day tour in tokyo, we will visit the following places (Tokyo Tower Observatory, Imperial Palace Plaza, Asakusa Kannon Temple & Nakamise Shopping Arcade (40mins) it will end at hamamtsucho bus terminal. After this we wanted to go odaiba via waterbus (himiko or hotaluna) to see the life size gundam. Im quite confuse which pier or port to go to for us to take waterbus and also to schedule of water bus. And how to go there if our last stop will be at hamamtsucho bus terminal. Do i need to book to secure my ticket?

1. We are going to stay for 2nights at hakone before our flight. What is the fastest way to go narita airport from hakone? Is there shinkasen straight to the airport?

Thank you so much!
