Because their booking website is SO BAD? I like going to the leisure centre, it's nice, the staff are pleasant, the facilities are good. I try and book online because its more convenient. But their website is so God-awful!! You can't book more than one adult per session (eg swimming), not because they've got some rule that only one adult is allowed (there is no such rule) but simply because their website doesn't allow you to book more than one adult because it glitches and can't manage it!! I have to make a separate account with a different email just so I can book both myself, DH and DC in swimming 😤
End rant
