Listen: the staff is friendly, the bus is clean, lots to offer while on the bus (I.e. beverages) but the tour is completely pre-recorded. There is no one telling you (in person) the history or significance of the site. That was a big negative for me. If I wanted to listen to a pre-recorded speech I would have just done a free walking/subway tour. A round trip is almost an hour. There are NOT many sights to see. The bus stops at particular places and you’d wonder why? Some of them are residential, some don’t even seem to have any landmark or significance at all. Maybe you could use it as a method to get closer to a landmark or the malls to shop - but I’m not sure why this company chose to mark a location as a “stop”. Lastly, every 5 minutes or so, the bus will stop for 15. This gives you a chance to smoke or do what you have to do. Obviously this to to ensure that there is sufficient coverage over their network to say that there is a bus at every stop every 30 minutes
