The tour leader was very friendly, and the itinerary was packed with sights. Some places, like Kouri Island, were a bit rushed, but that was unavoidable due to the distance. Also, if you're planning to visit the aquarium on the southern itinerary, remember not to buy tickets online yourself; the tour leader will give everyone a 30% discount coupon on the bus.
For this trip to the northern attractions, we chose the KKday one-day bus pass, which was very cost-effective. The tour guide provided detailed explanations, and there was ample time for the group to explore each attraction. If you don't want to rent a car, I highly recommend buying the one-day pass.
