For the week in Hokkaido in October, I am finding rentals really quite expensive. I just had a quick look at rentalcars.com to see what was on offer, generally. I still haven't got around to studying this and making a booking. I need to study this thread again, especially the post of beep88 (post #83 ). Actually, I am thinking of spending an extra night in Sapporo and cutting my rental time down to 5 days (still seems to be cheaper to rent from CTS airport). I reckon Sapporo deserves at least a day to visit it and probably a lot longer.
