6 person tunnel tent, where the sleeping compartments take up 1/3rd of the space, plus a porch that adds another 3rd (if it rains at Mildenhall, I suspect there's able room for everyone to hang out in our tent). Coffee table, enough fold out seats to host another family, twin burner and trangia, vegetable/storage rack, double campbed with integrated air mattress...
In our defence, we went camping when my wife was 7 months pregnant, and it's all her kit. We'd like some lightweight kit too.
