Actually, if there is one thing it isn't it's Blackpool, or Croydon on Sea.
Not a mobility scooter in sight, very few obese people around compared to the UK, zero unemployment, no-one on benefits, no Bingo, no betting shops, no really rough pubs, no people who look like they might appear on Jeremy Kyle any minute, no social problems, relatively little public drunkenness or fighting, (and when that happens it's usually thanks to the British/Irish doing what they do best 
) very little crime, no highly visible issues with drug abuse or homelessness, no mentally unwell people left to rot on the streets.
Everyone there is either on holiday or they are there with a purpose that gets them up in the morning, functioning and contributing.
I can't speak for the quality of the tourists but the expats who live there (and in Qatar where I live) tend to be professionals, nurses and teachers, people in management, self made business men and women or those who have highly sought after engineering and construction skills. That's why they are there.
You can say what you like about it, but it's NOTHING like walking down the high street of a depressing downmarket UK town with its boarded up shops and its air of menace and hopelessness.
