Sure, no probs with that... lots of car club people are coming, and thankfully the parking closest to the venue (North Road) is a multi-storey with full security and very gentle ramps and curves - I park the Z there.
Hotel wise, what's your budget?
Thanks for info Stephen , Re hotel budget not too bothered so long as it doesnt creep over £100 / night mark
OK then...
suggest for the 'full Brighton experience' that you look at Hotel Seattle - it's a very cool modern hotel built on Brighton Marina that looks out over the sea. See what rates you can find online, if they aren't too hot, I can see what I can find too.
