We took this tour the morning after we arrived - it was well worth it - the driver was very informative, knew the areas, gave a lot of information and it gave us a great idea of where we wanted to go back and see more of those areas.
If you are only in New Orleans this is a great way to get an overview of the area and to see the highlights the city has to offer. As it turned out, on the day we toured we were the only four on the bus...which made for a much more intimate and personal tour. As was advertised the smaller vehicle allowed us to go into areas and neighborhoods bigger vehicles cant get into. The driver was very knowledgeable and had a number of handouts to study on various people, events. That being said, it seemed he had a regimented agenda and our added questions seemed to throw him off a bit.
It was a good tour and I would recommend.
