If not in the good section, change it
I open the idea.
After some talk with other people, about the complexity organise a Eurobowl in Switzerland, most of the cause of price and space.
But I might have a solution.https://genevahostel.ch/fr/
It's in Geneva, 2 streets close to the lake, and 900m from Cornavin train station.
They have more than 300 beds, with rooms for 6, 8, 12 people.
After a few look on their website, I got a first price at CHF68/night with 3 meals.
So, I decided to take a look at the place.
The good things :
Easy access. (International Airport, Train station, Car Park)
Center of Geneva (lake...)
Not so expensive for Switzerland (close price of the other Eurobowl from last years)
Possibility for coaches to spend extra night(s)
The bad things :
Not the beautifulest building of the Geneva.
Conference rooms to small to play with more than 100/120 coachs (no Euro'open at same place)
Escape room at 200m (3 rooms to offer extra-activity)
My 2 cents
