Listed as the Travel Channel's most haunted cemetery. Tour prices run $20 with tours being at 10am. The time in the morning shouldn't be a huge issue unless April's been riding the mechanical alligator the night before. More to come on that later. :)

Departs from the Basin Street Station lobby

Founded in 1789 and listed on the National Register of Historic Places, St. Louis Cemetery No. 1 is located just steps outside of the French Quarter at the corner of St. Louis & Basin Streets. It is the burial ground of some of the most illustrious citizens of New Orleans, including Etienne de Bore, pioneer in sugar development; Daniel Clark, financial supporter of the American Revolution; Paul Morphy, world famous chess champion; and other local and national figures.
Notable structures include the famed oven wall vaults, the supposed resting place of Voodoo Queen Marie Laveau, and the magnificent tombs of the French, Italian, Portuguese, and Spanish societies.
Dramatically shown in the 1969 film, Easy Rider, the cemetery is the oldest existing cemetery in New Orleans. It is a maze of wall vaults, family tombs, and society tombs that artistically showcase the unique burial customs & traditions of New Orleans.

Although some of the reviews liked other cemeteries, it appears several are within walking distance from the French Quarter and a guided tour may not be a necessity. St. Louis Cemetery No.1 Closes at 3pm.
This cemetery's photos look amazing as well and is ranked a tad higher on TripAdvisor. Although, I have not researched its location in regards to our hotel.

While looking for a map of NoLA's cemeteries, I came across this.... Wow
