The Nemo Hornet 2 person is quite spacious. My girlfriend used the 2 person tent (just for herself) and we called it the penthouse suite. Lol!
I personally would get the 3 person, but myself and my husband are both +6ft. You could easily fit 2 normal sized people in the 2 person tent. You can’t go wrong with the Nemo Hornet... it’s $$$ but you save so much weight.
