IMHO spending the money on VIP tickets isn't worth it. Those tickets are aimed more at corporate entertainment and are therefore 'remote' from the true action and atmosphere. You'll get a better experience from a hedge or grass bank somewhere.

I've watched from the grandstand once and it was interesting though not an experience I'd want to repeat regularly. I think its something that should be done at least once, If you like it go again, if not at least you know what it's about!

whatever you end up doing I'm sure you'll have a ball!
