We just left a stay at Bayou Boeuf. It is a simple campground operated by a very friendly husband and wife team. All sites are full hook up, mostly 50 amp, with one row of 30.
There are several full timers there, but plenty of open spots for visitors. They have three or four "cabins" (really small trailers with wood siding) to rent that are very cute from the outside.
There is a washer/dryer room onsite.
It is right on the highway and near a train track so expect plenty of noise. But, for the price, the friendliness of the people there and the proximity to towns, you can put up it!
