It is good to stay here if you have an early flight the next day. Checkout takes literally 20 seconds using the machine and you walk out and you are already at Terminal 2. It takes 5 mins to walk to the free shuttle downstairs to it is another 10 mins and you are at either Terminal 1 or 3. The monorail or keikyo line are also very convenient to go back to Tokyo or Yokohama for a day trip, takes only about 30 to 40 mins.
