Greetings fellow travelers. Currently me and my wife are planning to rent a car and spend the night at Kii-Katsuura at Hotel Urashima. From there, we plan to do a day trip first to Nachi Taisha, Kumano Hongu Taisha and Tsuboyu Onsen.

Our plan is to commute to each places via car. Can I ask for some opinions if this is doable; and also how much time should we spend on each of these three places for the day? I have heard that for Nachi Taisha, some time is required to hike up to the shrine and the falls itself but can anyone confirm on this as we are driving?
