The Octagon has a mesh inner - so it will protect against condensation dripping on you, but will be chilly.
I have always thought the Rosewood looks a lovely tent.
It will be heavier and bulkier to pack than a polyester tent though. And slightly more complicated to put up than a bell. But better internal space than a bell because of the straighter sides. And it is a very good quality tent at a very good price!
