We were there on a very hot, humid day with the heat index above 100. There was no breeze but the Trolley Tour provided us with a place to sit, relax, learn some history, get great tips and some moving air.
During these covid times, we did not do too many indoor, touristy things so we liked the fact that the Trolley was open air and covered on the top if it rains. We chose to sit in the last seat in a section so that the people behind us were more than 6 feet away.
The reason for the 4 instead of 5 stars is because the drivers we had did not mention Stop numbers. It also seemed like the route doubles back a lot and that can be confusing because an earlier stop can be close to a later stop, even though they are different numbered stops. I also think it stops too early, or, they should maybe do a special route after 4:30 that has fewer stops but stops near areas with restaurants.
But, it is a great way to get around if you are not in a rush. We liked it!
