Ok, never camped before and actually never considered it. I need the loo in the middle of the night and camping is NOT conducive to that need of mine! 
However, I do have two boys (almost 5 and 3) who would LOVE it. And friends who won't stop recommending it. So I kinda would like to try a compromise, which is basically hiring a yurt in the middle of a campsite. Ok, ok, call it glamping or whatever...
DS1's 5th birthday falls on the weekend of half-term (the end-Feb end), was thinking of booking this yurt on a campsite not too far from us for 2 nights just as a 'trial'. Is that a really bad idea? In the past years, his birthday has always had brilliant sunshine and almost spring weather. But I've gone and jinxed it now haven't I?
I would have considered the Easter holidays but of course, anything from end-March onwards is already fully booked up...
I need some advice from those who have braved it in the colder months? Is it really that bad if it rained? As long as it didn't flood? Thanks!
