We got ourselves one of these for the 2 of us: https://www.decathlon.co.uk/p/camping-tent-2-seconds-easy-3-p-fresh-black/_/R-p-313048?mc=8576110
No way we'll be able to stand up in it, but as we're 180/190cm we're just happy it has space for us to lie down! Has a small outside flap, so should be able to leave boots there, if not actually sit there.
We gave it a test today. Very impressed. Take out and find the two umbrella like pull cords, pull and... pop! TENT!
More impressive, pop the umbrella thingies, and fold up like umbrellas, all very gently and simple. Hold them together, roll up.. and it went back in the bag without any issue!
