We initially bought a 4 metre bell tent but soon realised that the 5 metre with a separate bedroom inner would suit us better.
Easy to put up
Cooler in warm weather, especially as you can unzip the sides to allow air to flow right through the whole tent
Lots of space! Edl though it says it will fit 4 mattresses in the bedroom we can easily fit 5 SIMs in with room to spare, so easily enough sleeping space for 5 adults.
With a canopy on the front to extend the useable sheltered space this tent is HUGE and offers a lovely space to have a long camping trip in. Because its put up in less than 20 minutes (alone!) it's easy enough to take on just a quick weekend trip too.
Downsides: heavy and big when packed up! If it gets wet you need to have somewhere at home to dry it or it will go mouldy. Being able to remove the groundsheet does make this considerably easier though!
If you prefer to have a quiet holiday Tia might not be for you either as it will attract attention and children will want to play in it!
Overall I can't recommend it highly enough and I'm looking forward to going camping again soon!
