The driver was very friendly and informative. The ride gave us an idea of where everything was and things we wanted to go back and see.
The carriages line up at Jackson Square and the Garden District. We got on ours somewhere else. I think they're happy to pick you up wherever, so if you see an empty one, ask. It was a lot cheaper than the New York ones, especially if you have another couple in the carriage! If you want the carriage all to yourself for a more romantic trip, it will cost a bit more.
