This is a great tour. You see all the great places in the park and our guide was very knowledgeable about all things in the park. And really had some interesting information and stories that you would not have known if you were on your own. Plenty of bathroom breaks and lunch. And plenty of walking if you want. The van was new and well worth someone else doing the driving. There are something like 50+ switchbacks, so whoever is driving will not see any of .the panoramic views that are available. Great tour for the value.
