I know that this is largely dependent on the weather, but assuming a standard UK summer, (maybe a few hours of sun during the day, plus a bit of drizzle and mostly clouds) how prepared should we be for cold nights? Have planned on taking long sleeved/trousered pj's for our 2 dc's plus all in one snuggle suits and they have nice warm sleeping bags. But a couple of posts have really worried me and now I am thinking that this won't be enough!
(actually I am more concerned about DH as he can be a bit precious- and as this is our first camping trip I need to make sure it is a success otherwise all the equipment will be going on ebay the day after we get back!)
Make sure you insulate from underneath as well as on top. We usually have a foam mat, blanket, mattress, blanket, sleeping bag and blanket on top if need be. I often find that the first night is the coldest, then either the tent warms up or I get used to it.
