In reply to Ava Adore:
It depends on:
How good is the wall?
What other walls are there and how far away are they?
How much is the fee?
How often do they charge it?
I can't be bothered going to a new wall near us, because you have to pay £10 for an 'induction'. You have to make an appointment for the induction and can't just turn up. The wall is tiny and is run by the council, so doesn't have that lovely climbery cultural atmosphere, and there are other great walls nearby.
