I haven't camped since i was a child when airbeds were the only option. Am planning to take the 2 DSs who are 5 and 9 camping for the odd weekend. We have a little 3 man tent and I was planning to but 1 double and 1 single airbed and have found some Karrimor ones which are reasonably priced. I gather self inflating mats are better but budget is a consideration and if we are camping very rarely does it matter that much?
