This was my first chance to get my wife to New Orleans, and other than the fact the Quarter was only about 25-30% up and running (Corona crap) on a Mon/Tue night , this was definitely the highlight for my wife's visit.
The tour bus showed up a good 20 minutes early, we were all checked in and the tour started a few minutes ahead of time. The total mileage was probably only about 10-12, but fully half of the time was spent at the cemeteries listening to history and a plethora of great stories.
$45 (10/2020) may sound a little expensive, but when you consider it's a 2 hour tour, the seats are really comfortable, the driver knows the city, the guide presents the material consistently, and takes a few questions... I couldn't have been happier with the cost paid for the enjoyment and relaxation of not having to try and find these places myself... Even with navigation, NOLA is an interesting city (at best) to navigate, if you don't know it...
