I live 10 miles north of Brighton. Couple of tips if you are going.

By train don't walk straight down Queen Street to get to the seafront go via the North Laines www.northlaine.co.uk loads of individual shops, real pubs and street cafes.

By car. After the large roundabout at the bottom of the A23 the traffic into the City Centre from there is always busy and parking in the city centre could cost you £5 per hour.
Put BN3 2LS in the satnav and park right outside the Council Offices. Cost you £5 for 11 hours and you are right on the seafront at Hove with a nice walk along the prom into Brighton.

I'm in the home end Saturday with my Brighton mate at least I can shout 'Up The Albion'
