We bought the three day hop-on hop-off bus tour for $49 per person. It was worth it. However, I found out later that the AAA book has a coupon for $3 off per person. The first day we stayed on the bus the entire loop - about an hour and 45 minutes. We also did the Garden District Walking Tour with Paige, who was excellent. We had various guides: Teresa, Joel, and Craig, and they were all good. We got off at the French Market, the Gardent District, Canal Street, and the World War II Museum. The buses come fairly frequently early in the day and less frequently later on. Also, if you get on the bus too late in the afternoon, it may not take you to the stop you want to go to; the buses have to stop by 5:30 no matter what. Overall, I recommend this tour.
