Are the Proaction and Lichfield tents that Argos sell any good? I notice that the experience campers talk about Outwell or some other brand and I would like to know what differentiates an expensive tent (>£200) from a cheaper one? Is it the quality of the fabric, the hydrostatic head, the ease of erection, the weight etc. We are contemplating going camping next year when the twins are 3yo so any advice offered would be much appreciated. Eventually, we would like to go away for long weekends and a week during the spring and summer months.
