Put some old carpet down and pitch on that. Best idea is just go to a local camp site. Get some blow up beds etc to sleep on as you need to insulate your self from the cold ground, if you are skint Card board works and polystyrene Its a very good idea to list what you take and review what you don't need.
We are buying or first tent tomorrow. Been camping a fair few times before but always in a borrowed tent. This will be the first time camping with DC so we'd like a practise ruin at pitching and sleeping in it to check we won't freeze.
Our garden while big enough for the 5 man tunnel tent only had a patio or bark areas. Can we pitch the tent on either of these or will it rip the groundsheet?
