We visited Knossos the lazy way, on a tour, and that was a bit disappointing. Half the tour was in German meaning that you just stood around half the time wishing you could be exploring the site more and also the route through the site was pretty constrained so I feel that there was more that I could have seen. Serves me right - it wouldn't have been hard to get the bus, just laziness.
I also had plenty of time to research my new book which I am getting really excited about. I've decided to save starting it until Nanowrimo in November.
