We use this as our "luxury" car camping tent. I did a lot of research to find a tent that is tall enough for my 6'2" boyfriend to stand up inside. This was the tallest one I could find and we are really pleased.
It's easy to set up, the carrying case is great, and it has a nice balance of privacy and mesh for ventilation. The little skylight in the fly is a nice touch and there are tons of interior pockets. It survived a decent thunderstorm on its maiden voyage with no leakage.
I noticed a little condensation on the floor the first time we took it out, so I bought the footprint and that took care of it. It's probably better for the life of the tent, anyways.
I think this would be pretty cozy with four adults. Our BA Dream Island double sleeping bag takes up a good chunk of the floor space (granted, it's enormous), with some room for bags and such. Overall, this is a great tent and luxurious for two people!
