Spending Shabbat in New Orleans seemed to be the biggest challenge if we wanted to be near a shul. There are a few orthodox shuls, but none are walking distance to the hotels downtown. Before our plans were canceled we had planned on staying at an AirBnb in the Uptown neighborhood near Tulane University, walking distance to the Chabad in that area. The houses in that area are quite nice, so that would’ve been a treat.
The other options were Anshe Sfard in the Garden District in a beautiful synagogue, or one of the 2 orthodox shuls in Metairie, the Chabad there, or Congregation Beth Israel. Both are near each other and in an eruv, but the hotels in Metairie are not in the eruv and a healthy 30+ min walk away. We were told that while most frum people live in Metairie, there isn’t much to see or do there for tourists.
If you opt to stay downtown, you can get food catered for Shabbat by one of the aforementioned kosher restaurants, especially Kosher Cajun or Casablanca.
