Positive or Negative, I've never had a review rejected or edited in any substsntial way.
Not all parks are reviewed on a frequent basis, so one negative post that complains about one worker's attitude could stand alone for quite some time. Employees come and go, so basing most of the review on one persons attitude could do damage when it shouldn't. So a policy is in place that ensures the reviews also talk about other things that would be important to someone wanting to stay at the park. Is the way its handled perfect? Maybe not, but policies and guidelines need to be in place so there will be consistency.
I for one will continue to use the site, and to contribute to it. Like most people, I sift through the information provided and ulitmately make my own decision, but I do like having the input from RVPR.com
