The plan for overnight accommodation that weekend would depend on the turnout and your personal preferences.
Since there is no camping facility at the club, we will need to move.
Plan A would be offering you room in my house(-s).
Plan B would be finding a suitable camping in the nearby place called Bredene. I'll go scouting a few shortly to find out which one would be best for the event.
My aim is to keep the cost down, make things simple and easy and avoid scattering the party... Work in progress.
No problem for the boat, if not at the club it can find a place in my workshop.
