Andy,
Can you give any more info on the Laguna dates? what's the script etc, I'm guessing it's the same as UK CSS, do they have helmets and leathers also? or do you need to take your own? I'd prefer to take my own, but the whole airport weight allowance thing would be a 'mare.
Plus I would probably want to go for at least a week, and do the dates at the end, once I've got over the whole jet lag thing.
