Sorry, do not agree with the throwy Quechua tents, yes they are probably great for a one/two nighter but really do not work for more time than that. Quite obviously they are practical as far as erection etc. but the limited amount of space for storage etc. is not good for a long period especially when bad weather is involved. I used a three man tent, for my own use only, for a few years and while this had a little storage area in the front porch it could not be stood up in you could only kneel. This tent was easy erection with built in poles, and I did enjoy it, BUT, crawling out of it in the rain into muddy grass is not a good way to start a day, also if you are 18 stone movement is restricted. I purchased a Quechua tent from Decathlon a few years ago and it was a bargain at £60 now €99, this has a sleeping area which easily take a double blow up bed with plenty of room around plus a reception/living area, which you can stand in, which is great for your cooker/chair/table etc. and the door converts to a canopy which is great for when it rains (as proved in Spa a couple of years ago) though I would suggest the use of a B&Q £13 gazebo in conjunction with this for when friends pop in.. I would suggest that the extra time it takes to put the tent up and dismantle is well worth the hassle.
So Chris I would stick with what you have, why not borrow a throwy tent from a friend and sleep in the garden for a few days, that will make your mind up.
Bigger is better, trust me.
