Was enormous!!!!
But there is no way it would sleep 8. It has two proper sleeping pods (one at either side) which you could squeeze three people in each but only if they didn't want blow up mattresses. The third sleeping pod is at the back and is pretty small - you could get one person in (not the two as stated) but they would have a face full of tent as it only attaches at each corner so is pretty saggy. It is perfect for storage though.
The living space is huge. You could easily get a cooker area on one side of the entrance (the entrance is a little like a porch which opens out to the main living area) and store things on the other side and still very easily get in and out okay.
The main living area is vast. You could get 8 people sat around a table easily.
It took the two of us about an hour to put up - which we didn't think was bad for a first time and I took it down myself. It took about 90 minutes for me to take it down and pack it away but that included emptying it first and letting the air beds down, etc.
It was really comfortable (for a tent) and Mick really liked it.
I did get some photos of it so will try and get them posted tomorrow (my phone is currently lost in the house somewhere!).
