In reply to Nordie_matt:
I recommend the current vango range.
http://www.vango.co.uk/gb/37-family-tents-poled# these are really good family workhorse tents (In my experience better than Outwell and rubbishy brands). You can usually see them put up at tent shows, Cotswold and Go Outdoors etc. I use the ones with poles rather than the airbeam ones. we have a green 4/6 person one, I think its an odyssey 600 or Iris 600 (not sure). had it for 2 years - has given good service in Lakes, Northumberland and Scotland.
I rate them highly for the following reasons:
good price
good space for extended trips with lots of comfort and space for kit, chairs and generally slobbing around.
easy to put up
good weather/water/windproofness - lots of guys!
very midge proof (integral ground sheets so you get a good seal, but with meshed ventilation options) We cook inside all the time with kids and dog - obviously taking precautions!
easy to transport - not that big when packed.
My family is v v happy with ours. for me its the best compromise I have found of the above criteria after trashing several tents over the years.
ps the airbeam ones look v.interesting, but more expensive and Ive never had one before so am loathe to part with my cash as an experiment.
