I purchased the 9 person instant cabin tent for a two week camping trip for 4 ladies. It took us an average of 15 minutes to set up and take down. Roomy and comfortable. A thunderstorm came through and our neighbors had to dry everything while our tent was completely dry.
There are two downsides: the first is that you have to be very careful when lifting the legs in setting up. Somehow I managed to snap one of the legs and I wasn't even pulling hard. The other is that the top is mesh for viewing the stars. It's a nice idea, but how do you put it up in the rain without getting the interior wet? We tried leaving the rainfly on--don't do this! It gets tangled in the legs.
