For the ceremony and event think 'spring-garden-cocktail-party'. New Orleans does tend to get warm as summer rounds the corner, so keep that in mind. We recommend light clothing but keep a light sweater on hand (air conditioned buildings tend to get chilly).
YES! Wedding guests will be allowed to go inside the mansion before and after the ceremony. We ask that you please be respectful of the mansion, its a beautiful location and we cannot wait for everyone to see inside.
New Orleans has plenty of options for transportation. Easiest option would be using an Uber/Lyft app. Another fantastic option is using the historic streetcars around town. We recommend using the St. Charles Streetcar, it runs across the city and can get you to and from the Garden District to Canal Street/The French Quarter.
