I ignore the reviews that rate the campground 10 stars, and read between the lines on the rest. The reason I toss the glowing reviews is because every CG owner has at least a few friends to shill for him. ;)
But sometimes, the worst rating is a good review in my opinion. Last year, I read one that gave the park one star and said they would NEVER stay there again. Seems the owner made the camper keep his large dogs on leashes and insisted he clean up behind them. To add insult, the owner also required the camper to turn off his outside entertainment system at 10 pm. The nerve of some owners! :B
