The bus tour was great but when you book through Viator.com you must be aware that the picture you see on the site is not what the bus looks like. The bus is a bubble gum pink double decker and you can catch the bus at any of the locations you don't have to go to the beginning. The funny thing me and my friend were the only ones on the tour and the guides didn't even give us the tour they just kind of gabbed to us, but it was fun just the same. I would surely do this tour again. Also plan your trip when riding the bus, we had a lot of wasted time and didn't get to see half the things we wanted to see! Get the route and plan accordingly, it is just 1 big loop. Recommend the city pass along with this because it hits pretty much EVERY attraction you want to check out...touristy wise.
