Day trip to Kumamoto

Today, two other professors and I are going on a day-trip to visit Kumamoto Prefectural College. I will be picking them up at the Bunkyo campus at 7 AM. From campus to campus it should be about 2.5 hours by car (200 km).

I would prefer the southern route, which goes through Shimabara City, and use the ferry to get to Kumamoto City. This  cuts the distance by half, but actually takes 30 more minutes, since there are no expressways to Shimabara.

Originally we were planning to spend the night there, but things change. Oh well, I have been through Kumamoto many times but yet to stay overnight.
