We stayed at Lake End park a couple of years ago and wouldn't hesitate to return for a month or more. $450/mo isn't a bad price at all for a decent FHU CG that certainly isn't a dump. BTW, the cooler thieves were coming in boats, not through the front drive. I'm surprised they didn't meet Messers. Smith and Wesson or Mr. Remington.
The north wind off the lake can get mighty brisk.
Otherwise we'd likely go up toward Lafayette / New Iberia / Eunice etc but some of the CGs there are rather high-priced.
