What I 've noticed is that all reviews are still shown, but that older reviews have less influence on the parks average rating. They still have exposure, just less weight in determining the current average rating review # .
I think this is a good policy, in RVPR. It reflects, emphathizes today, vs yesterday. Private Parks / Camps change ownership on national average of 4.7 years. Each time, the new owner looks at the BUSINESS differently, with growth, income, or other value such as development property other than as a camp. It manifests that change of management a shift in policy toward that end .
What do you value? A flame or glowing review from yesteryear or yesterdays?
If only the last 2 years reviews on Trip Advisor.com were shown on our camp, we would be # 1, of 22 instead of # 11 on our area.
Navigating the new site is just a learning curve, gives more.
