I spent a week there once, a little over 20 years ago.
The trams are an attraction if you like that sort of thing (as I do), and a slow evening drive along the Golden Mile to see the illuminations is a must-do activity, but other than that it's really not much different from any one of dozens of other seaside towns. Not that that's a complaint, since the whole corny fun-of-the-fair seaside resort thing is one of the best things about Britain in my opinion.
