We are just about to return to the San Giorgio for the thid time, and from the comments on this site it sounds as great as ever.
Further to my last entry we have just returned from Kef, and the San Giorgio which was as good as before, if not better.
My suggestion is do not organise any car hire through the tour agents as this is an extremely expensive way of hiring a car. I have just arranged a weeks hire for €145 inclusive 7 days hire.
