We were there last winter and it was wonderful, especially Avery Island. We stayed at a hotel so I can't tell you about RV parks, but after you visit Avery, go check out the Conrad (Konrike) Rice Mill, in New Iberia, and take their little tour. After you will be so hungry for Gumbo, ask directions to the best gumbo in town. We did, and found it only because the lady told us to watch for a RV sales place and it was next to it. Glad she mentioned it as the restaurant's sign had faded out years ago, but OMG the gumbo was awesome. I still think about that gumbo.
