@Stan Galat We, too have done a tour of UK and had a blast. We were there for 2 1/2 weeks with an open-gate ticket into London and out of Glasgow. The hardest part was cutting locations out of the trip which would have just rushed the whole experience. I rented a car, which others suggested I didn't and it was one of the better decisions I made. We are discussing a potential 2nd trip to see what we couldn't the first time.
For the Tour, unfortunately; I have to be non-committal right now. There are a few considerations I have to make for both the location and the time frame. There are some other things that would need to fall in place to get the Spyder there. That doesn't mean I can't bring the Cayman instead if that is the only obstacle. Count me as a "maybe" and I will let you know if I am in as soon as possible.
Is there a hard date you need to know by?
