This will hurt later

Safely on board the unreserved part of the Hikari Superexpress 400 departing Nagoya at 6:20 after being told last night there were no reserved seats left - smoking or non-smoking - until 8:30. I need to be in Narita as early as possible, which from Nagoya on the first shinkansen of the day is 10:00, to meet Dad. At least I now have plenty of time to change at Shinagawa.
