How structured should our itinerary be?

We are headed to Tokyo via Haneda Airport in March and e have a, general itinerary planned. Hotels booked. A couple reservations for Nintendo Museum, sumo show and Disney. We have a general idea what areas we are going to visit each day, but we don't have anything down pact. We're going with a casual approach. We will be there for 11 days with a 3 day stop in Kyoto. Other than transportation, is going casual with the itinerary ok?
