(Blackpool, Skegness and Bournemouth all beat Brighton. Now, before anyone from Brighton gets on their high-horse, it lost because it's so trendy, has dreadful parking and is full of clubbers. I don't think anyone can argue against that.
A traditional British seaside experience should include sand in your sarnies, "Kiss me quick" hats, a 99 cone, sticks of rock and chips and mushy peas on the beach. In Brighton it's more pebbles in your champers, Gucci bags, sorbet, chocolate truffles and a skinny latte on the terrace.)
