I was a little dubious given some of the reviews, and it wasn’t perfectly seamless, but after the first view sites we got into a rhythm of toggling back and forth between mapping and sites. When tour buses are safe again, that may be a better option, as we couldn’t see over some gates from our car. But $5 was a great price for a 90-minute, air conditioned, family activity with art, history, culture, geology, and navigation. And that was only one tour, there’s still two more we can do!
