I'll have my 3x3 gazebo as well.
Just a point - the campsite charge £5 per night per gazebo, so we would be better off with the 6x3. On the other hand, split among all of us, the cost becomes incidental.
I will also have a small gas BBQ - but it's not big enough for a mass cook-out!
There's a microwave in the 'van which may be useful, but keep Lawnmower Man away from it!
