Camping

I have that decathlon one. Its good, forgot to by a pump and had to borrow one on first trip using it. The bag is pretty big and its heavy. Only suitable for car camping.

I’m on a similar hunt and have 95% landed on this Alpkit one:

Yes it’s Alpkit so the usual it’s-just-a-Naturehike arguments apply, but it’s the only family tent I’ve found that uses backpacking tent style design without costing a billion pounds.

I would go for this, which is lush and black out but packs down small.
You really don't need inflatable until you get to 6 man size I reckon
