*nod* Yep, some of my California chums are heading over to it. Had things worked out a little better - if The Swain had found employment in time, etc - we would have gone too. Woulda been fun to hang out at a convention with my chums AND in the UK, simultaneously!
For an amusingly awful eyesore, visit The King and Queen, a frightful mock-Tudor pub in central Brighton that's a long-established landmark. And don't skip The Pavilion and the museum of Brighton. :)
If you can get up into the Downs, you'll get some gorgeous views of the town and the channel. I used to take riding lessons up by the Brighton racecourse and, damn, that view couldn't be beat (indeed, it's one of the reasons why the racecourse was located there in the first place...)
