Rolf-Dieter,
The Euro Event is from 27 to 30 September 2018 so an August date could work well for me as I was planning on spending at least a month or two before hand around Spain, France, Italy, Croatia, Czech, Poland and then maybe Scandinavia before heading home.
Artur, Where are you holding the event. Pretty sure Kate and I will be where ever it is.
