My family, 4 adults and 2 toddlers, will be visiting Denali on May 20 and 21. The only shuttle bus running at that time is the Toklat River bus at mile 53 with a cost of $22.50 for adult and free for children under 14. On the other hand, both the Natural History and the Tundra Wilderness tour buses are available on those dates for $52 and $94 respectively for adults and half price for children.
Question 1: Other than the tour guide, will the tour bus take us to different sightseeing spots than the shuttle bus?
Question 2: Should we take the AM or PM tours for better wildlife viewing?
Since the cost for the shuttle bus is much cheaper than the tour bus, we just want to know if it's worth paying the extra money for a tour guide. We're not planning to get on and off the shuttle buses as we have to bring along our car seats.
Any advice is welcome.
