Recommendations for Hen weekend in south- yoga/foodie/glamping type hen!

[Drivingforpeace]

Hi all, any ideas on where we could take our lovely hen for an overnight stay somewhere within about 3 hours of London in late September? There's about ten of us and we are mid thirties, mostly with young children, including her, so one night away I think . She's into yoga and she's arty and she would love something in the great outdoors, she's also a foodie, I'm thinking glamping somewhere beautiful...... Perhaps with some beauty treatments too?! Any ideas? Thank you!
