Chris,
yep, I'm from Brighton! I now live about 15 miles away. Places to visit? Depends what you're after I guess - Lexus Brighton maybe?! In town there's loads of decent pubs and places to eat, the pier, shops, Brighton Marina, Pavilion etc. Out of town there's some decent countryside if you prefer the fresh air - the South Downs, Cuckmere Haven, pretty villages and so on.
When you get your passport stamped give us a shout if you need more info!
