No our local (5 min and 10 min drive) cinemas are £4.99 a ticket we go regularly and its just DD and myself. The larger cinemas in the city are an hour each way so more of a day out timewise or If we were a larger family and it cost £££ then yes.
We go to the theatre roughly once a month,that's more of a treat if combined with a meal out. I have a Friend's of the theatre card so for £25 a year, I get 50% of the first night of productions or other discounts for other days so makes it very affordable
DD is autistic, only does rugby as a extra curricular which is cheap so I see regular cinema and theatre like an additional extra curricular that we both enjoy, it's our 'thing' and we massively missed it during COVID.
