Sounds like a great trip!
I'm in Australia and finish high school in a month and had been planning to do a similar trip next year (Le Mans, Monaco, N24, Spa, Isle of Man, Pretty much as many events and places as I could get to). Just the slight problem of $$$
I'm still clinging onto the small hope that it can and will happen next year, realistically though...
Good luck! I'd love to hear of your experience and any tips you have to share!!
