Agreed, the Quechua 2 seconds stuff at Decathlon is great – we’ve had plenty of use out of ours between festivals and weekends away. We have an XL which has a small porch (good for boots, chairs, etc) or they do an XXL now with a bigger porch that would be big enough to sit in.
They go up very easily, for folding away just watch their video on youtube – it’s easy once you have the knack, and it’s hard to explain in words and diagrams on the instructions.
Only downside is that the packed shape (a big disc) makes it useless for carrying far, but really they’re the ideal car-camping tent.
Get decent camping mats and take extra blankets or a duvet – women tend to feel the cold more and it can still get pretty chilly at night in summer.
