The Wedding will be at The Music Box Village at 4557 N Rampart St. This is in the Bywater neighborhood. There are many AirBnBs as well as Bed and Breakfasts in the neighborhood.
Staying in the Bywater or Marigny would put you close to the venue and French Quarter Hotels aren't far away either. There are too many restaurants and music venues in this area to mention. Feel free to call me or Kathy if you have any questions. There are a l ot of AirBnBs (small houses and apartments) as well as cute Bed and Breakfasts in the neighborhood. Sweet Olive is very nice.
