We went for the so called glamping (aka pre pitched) option of Sticklinch because we are old and apart from the campervan option the only way we could physically do it.
I was surprised at how many younger folk chose this option, I expected a slightly older or overseas crowd.
Anyhow I agree that more pre pitched camping would skew the demographic to older and wealthier, which is not a good thing.
We are hanging up our boots now, this was our last Glastonbury I reckon.
