This weekend I saw this tent:
Biggest tent I’ve ever seen!
It’s a bit hard to tell but the tent the other side of the middle dome was the same size as the one on the near side. Plus there were two spurs going from the side. It was enourmous!
What’s the biggest tent you’ve ever seen? Send me a picture! Bet no one can beat this!

I saw this 20 man tent in Argos while browsing their half price camping sale. It has 10 bedrooms! http://www.argos.co.uk/static/Product/partNumber/9275812.htm
Good one Emily, can you imagine getting this one back into its bag!
