I understand that the English translator of Adventurous Heart II and The Forest Passage will be part of the group, as well as directing members of the Association Eumeswil itself.
They have engaged a world-leading travel expert to plan and execute the trip, and they're offering the tour with a very comfortable level of hotels and dining.
It sounds like a very interesting opportunity, I wish I had known about it earlier: the sign up deadline is in just 3 weeks, October 16th.
Working on going myself. But I don't manage it this year, they'll hopefully be offering more trips in the future.
