About 20 years ago I went to Blackpool as a teenager.
We spent a few days there and did the Sandcastle waterpark, the Tower and circus, the Pleasure beach, Madame Tussaud's, we rode the trams and went in the arcades. It was tacky but fun and I don't remember it being that rough or run down, but I probably wouldn't have noticed as a teenager.
Every now and then I think "I bet my kids would love Blackpool", they'd love the tower and the waterpark, then I google the place and read how everyone says it's an utter dive and run down, really rough and full of drinks and addicts and I think perhaps it's better I leave Blackpool as a nice memory in the past!
