Remember to check the price from SAS/Blue1. They have a discount for this event, but I don't know how much is it from England. If you are flying to Vaasa, I would recommend to go via Stockholm. I checked the price from Blue1 and Manchester-Vaasa-Manchester was around 280£ without discount. The timetables are not the best possible, but we are sorting it out with SAS at the moment. I think
www.amadeus.net is pretty good place to find flight timetables.
The road from Helsinki to Vaasa is pretty good. It's 400 kilometers so it takes around five hours to drive to Vaasa. Only problem is that there are plenty of speed cameras on the way
BTW Jimmy, we have a free internet access at the track for you
