House Or Rental
A reasonable lodging option would be a private rental through VRBO or AirBnB. (There seemed to be more options on VRBO when we checked.) Make sure you put in the exact dates you're looking for. SInce it's considered a holiday weekend, most of the properties have 2 or 3 night minimum stay requirements.
Hotel
We do not have a room block at this hotel but it is located less than a mile from The Terrell House B&B where the ceremony and reception will take place. It's also a good option outside the French Quarter where rooms will be much more expensive.
