The area known as Thanet (which includes Margate, Ramsgate, Broadstairs, Westgate and Birchington) varies greatly. It has suffered a slow and ungraceful decline in recent years, in part due to the decline of the British seaside holiday, for a variety of reasons. The main attraction used to be the sands and Dreamland pleasure park. However, the park suffered extensive damage in a fire and was never rebuilt and the sands are not that large, so get very crowded. Thanet was such a depressed are that it was given a grant from the European Development Fund. Thanet council has tried with mixed sucess to improve the area, allowing developments of Westwood Cross shopping centre (half way between Margate and Ramsgate) and promoting the new Turner Contemporary Art gallery. Broadstairs has a fine tradition of festivals and hosts a folk week each year showcasing some of the best talent around (and they're not all long haired hippies or tambourine waving wierdoes with their finger in their ear singing sea shanties lol) Not far away is Quex park, which has events all summer, and the Margate Winter Gardens still has a wide variety of shows. I suppose one of the main faults is the area is out on a limb, and the road links aren't great.
If you are looking to relocate to East Kent, why not take a look at Whitstable?
