Are there any treehouses that sleep 3?

[imsorryiasked]

I would really love to take DH & DS to stay in a treehouse for a couple of nights, but the only ones I can find in the South of England sleep 2 (apart from Chewton Glen which are £1000+ per night ).
Any suggestions? I've thought about leaving DS (or DH) at home but decided against it

Alton towers have just put some in for this season but I don't know how many they sleep.

Also forest holidays do some?

Thanks, Alton Towers is a bit too far away. I've just had a look at forest holidays but sadly the only one they have available on our dates sleeps 10 and is hugely expensive, (even their smaller cabins are £800 for a weekend)

Have a look at Canopy's and stars website they have all sorts
