I'm not a big tour bus fan, but this was fantastic!! The audio guide was wonderfully educational…read moreand the ability to get off and on at all the locations really made it worth the purchase of the tickets. For the most part the times were really reliable as well. One of our locations the bus was about 20 minutes late, but it was beautiful out so we didn't mind. I would highly reccommend this if you aren't familiar with Stuttgart. You won't be sorry. It will help you also decide if you want to do some things in more detail.
