You should definitely go... it's not a long trip, will give you a chance to widen your boundaries and on top of that you'll meet lots of people with good information and that all love C&Cs. On top of that local brokers and vendors often put on seminars and talks - there's usually a pretty full program at these things.
It's a nice harbour, the marina owners are very helpful and outgoing... do it. You won't regret it.
".. there is much you could do at sea with common sense.. and very little you could do without it.."
