Interesting!
I guess Colmar is a little south of Strasbourg. A chance to maybe get to dance with Alizée???? You'd certainly get to see her up close. If it wasn't for my age, I'd probably be packing my bags right now...............provided I could get a ticket.
Looking at Mickael Marques facebook page, it looks like he does this type of thing quite a bit, especially teaching Salsa.
I couldn't find any info on how to get tickets.
I believe this is what the inside of the facility looks like. Maybe you wont get close!
