Just back from Japan
Just got back yesterday so I have a ton of information. While in the end we decided not to go to Expo (we were staying in Gifu rather than Nagoya) I did pick up a leaflet that outlined 3 travel options from the Nagoya station. If you're interested, I can bring fax them to you, or can just tease out the information and post here.
Also unhappy...since our flight originated in Chicago seems like we are ineliglbe for United's SF - NGO double points (because the ticket doesn't list SF as a stopover)~ There are times I really hate United and its silly policies.
