Recommendations for glamping somewhere south of Manchester

[CatBlaster]

We are looking to do some glamping next year and would like to maximise our chances of getting weather slightly better than what we're used to in Manchester.

So, we're thinking of maybe Wiltshire/Somerset/Devon or South Wales - can anyone recommend anywhere with big yurts or bell tents for a family of 5?

We've just come back from staying at Irongorge Campsite, just outside Iron Bridge Shropshire. Not sure if it will be that much warmer but there loads to do around there to occupy a family. Not sure what you are looking to pay but these seem very reasonable to me.
Great site. Only just opened so the toilets etc all in great condition. They provide fire pits for the evenings which is key for us. We stayed in a pod but there were bell tents and one of the familys staying in them said it was fantastic and loads of room.

that place looks lovely Sally. What kind of stuff is there for kids in the area?
