Thanksgiving in Louisiana

Coushatta Casino in Kinder LA has a beautiful RV park. Very reasonable rates. If you get a players card they will comp your site, just call them when you leave.
In New Orleans we like Pontchartrain Landing RV park. There is a regularly scheduled shuttle bus to and from the Park to the French Quarter, Harrah’s Casino, and Downtown New Orleans seven days a week. For a nominal charge per day you can purchase unlimited trip passes on a daily, weekly, or monthly basis.
Mulate's Restaurant in New Orleans has live music.

While not SE Louisiana, Buccaneer SP in Miss. is very nice and you have multiple casinos nearby. Several of the casinos there have RV camping but never stayed so can't comment on those.

We like it around Breaux Bridge, usually stay at Poches Fish and Camp. Awesome food, great people, cheap, good RV spot. Lots to see around there. Tour the Tabasco Factory, Shadows-on-the-Teche mansion read some James Lee Burke books before you go. The southern Louisiana Casinos didn't do a whole lot for us but to each their own.

L''Auberge Du Lac casino has two locations: lake Charles and Baton Rouge. I believe the lake Charles location has RV spots... Don't know about BR.

Thanks I will check them out

try: Cypress Bayou Casino, Paragon Casino, Coushatta Casino, also non Casino Cajun Palms RV resort...kind of between Baton Rouge and Lafayette. I've stayed at all of these many times.
