My wife is a scientist and was invited to the Lindau conference for Nobel laureates. While this is a fantastic opportunity, I've been asked if I want to accompany her to Lindau for a week while she attends the conference.
I've been told I'll be unable to attend any of the events, and the days typically are booked from 8AM until 8PM. I suspect I'll have a lot of time on my hands.
Is there anything people might recommend I do while visiting Lindau? Please be aware that I will likely be travelling alone during my visit so preference to things that make sense to do alone.
Added Context: It will be mid-end June. As far as my own interests, drinking/social, technology, and any sort of unique experiences (things I won't get anywhere else such as local customs/traditions).
