I hope she is extremely tolerant of mosquitos the size of cocker spaniels and gnats. In all seriousness, if you're looking for a true "romantic" experience for her in Louisiana, do yourself a favor and stay in the Quarter, Hopedale is a 30 minute ride and I can tell you from many experiences with my wife, a much better alternative. The entire area is still on the rebuild and it's not nearly as aesthetically appealing, yet, as it was before.
That being said, If I had to take my wife down tomorrow the top places to stay and guides I'd hire would be:
Hopedale/ Delacroix
Capt. Charlie Thomason Or Capt. Gene Dugas and stay at the Silverside lodge. There are no restaurants in Hopedale or Delacroix yet. Chalmette's not far but those cops don't play around down there. If you wanna beer with dinner, keep it to one. If you can cook, there is a ton of crabs/ shrimp/ oysters to be had for way cheap.
Empire/ Buras
Capt. Matt Caire and stay at the Delta Marina. The accommodations aren't exactly five star but the restaraunt has some pretty damn good food and the bar has good drinks. Don't quote me but I think Matt will come pick you up from the dock at the marina which means you have to walk 15 ft and get on his boat.
Ponch/ Lake St. Catherine
Capt. Eric Dumas Or Capt. Miles LaRose. Stay in New Orleans and these guys will put you on BIG trout in the lakes. Probably the easiest fishing to be had in Louisiana considering the location and accommodation choices.
Bay St. Louis, MS
Capt. Sonny Schindler. Bay. St Louis is a quick ride from PCOLA and he's gonna fish you out of the Biloxi Marsh which is ,loosely, considered everything east of the MRGO. They have a camp on a back bayou that's nice and clean. Some restaurants around and the 2nd cheapest prices for shrimp in N. America.
I hope this helps and if you have any questions, pm me.
