Carl,
A lot of English seaside towns developed off the back of the Industrial Revolution, especially in the Midlands and North, where anyone wanting a holiday from the mills and factories would go for a couple of weeks. This though does mean that even a hundred odd years later, most of these towns have a bit of a cheap feel and its all arcade machines, caravan sites, candyfloss and fish and chips. Its certainly an experience though, and while Blackpool does nothing for me at all, there are certainly some decent courses on the West Lancs coast...
I'm going to back up what a few others have said. If you ignore the "towns" element, then the north Norfolk coast is a good bet. Royal West Norfolk (Brancaster) and Hunstanton are great links courses, and while Hunstanton may have a touch of the feel of what I've described above, many of the smaller towns / larger villages along the coast are delightful, Burnham Market and Wells-next-the-Sea for instance, and the beaches at Brancaster and Holkham are excellent.
Cheers,
James
