My wife and I had a great time going stop to stop learning about the city. Each guide had a different story to tell about certain areas, and they were all very well versed on the subject matter. We rode 4 different busses, with the last big red bus not having air conditioning, which was terrible since it was over 85 degrees on May 29th. I understand that things happen but the female driver told me the bus wasn’t equipped with AC, which I find absolutely unbelievable. I still think the service was amazing and silky smooth, and would definitely use the service again.
