We went a few years ago, pre-covid, and I was really impressed at the level of cleanliness and visible cleaning staff there keeping on top of it. When we went last year it had noticeably declined and was really grubby in places, the pool changing rooms being one of them. The floor was minging with puddles of standing water, hair, food wrappers, used swim nappies, sticking plasters and the like strewn around and seemingly no one cleaning it up.
I'm not going to mention anything to DD about it just yet, will see what unfolds this week as to whether it worsens or improves.
