Hi, need some advise from experts here regarding Mainz. My colleague and I will be going Mainz for a conference and arriving on a Sunday real early in the morning.
Thus wondering what we can do there and if any shops will be open on Sunday for us to shop around? This is the only day we have free so wants to make full use of it.
Or are there any half day tour available that we can engage in? Though we are not really into museums kind of sightseeing. ;)
