Where should we stay?

At this time, due to a big convention in town, our prior block reservations at the Sheraton have been canceled.
At this point, until we're able to lock down block rooms, I'd suggest finding accommodations in the Central Business District, Mid City, Lower/Upper Garden District. (safer neighborhoods).
The ceremony is at Grow Dat Farm-a venue in City Park, close to Mid city/Gentilly neighborhoods. There are not hotels near here, there is some great/cheaper Air bnbs that would be perfect.
Typically, out of towners stay in the French Quarter-Lovely & must see, it is very close to "all hours" Bourbon Street, higher hotel prices, & not very family friendly.
Top suggestions
Air bnb in the above neighborhoods.
Holiday Inn Express St.Charles
Astor Crown Plaza
Courtyard Marriot
Embassy Suites
Hilton Garden Inn or Riverside
Spring Hill Suites Marriot
Do not book hotels in Slidell, Algiers,Gretna, or Kenner. Very far away. Nor 9th ward, Treme, or Gentilly. Can be dicey at night!
