Crowds & Timing
During festival seasons (Mardi Gras through spring), New Orleans can get very crowded. Think about fall or early winter to avoid crowds (6). Fall is an excellent time to avoid crowds and the sweltering summer heat, as suggested by travel guides (6). Aim for late afternoon or evening during the day; for instance, Jackson Square is captivating at sunset and almost deserted after dark (2). On weekdays, however, it is quieter in City Park. You can get better hotel rates and more privacy if you book outside of January or September, when most tourists travel.
Permits & Reservations
Permission is needed for some locations. The Peristyle and Botanical Gardens in City Park are stunning, but proposals require permits (4). For information, get in touch with City Park Conservancy. Proposals are welcome at a lot of restaurants and rooftop bars, but to avoid drawing too much attention or if you need a private corner, always call in advance. You frequently need to make reservations or know someone to gain entry to private courtyards or mansions. If in doubt, a local wedding planner can assist with obtaining permits, making reservations in advance, or even discreetly reserving the Peristyle for a single hour.
Weather
The weather in New Orleans is erratic. While winter is mild but may see rain, summer is hot and muggy (think July storms). Choose a covered area, such as the City Park Peristyle, if rain is predicted because it is "covered so it's a safe bet for a rainy day" (4). It's a good idea to have a backup plan in case things go wrong. A romantic restaurant or a hotel lobby, like the one at the Roosevelt Hotel, can be used. Keep umbrellas close at hand and consult seasonal forecasts.
Privacy
Consider the public versus the personal. Avoid crowded streets during lunchtime if you're a privacy freak. A sunset boat ride or early morning Bourbon Street are two examples of more sedate locations. Many NOLA locations get crowded if you visit off-peak, as local guides point out (2). Additionally, employing a planner or photographer can provide cover by claiming that you are doing a styled shoot.
