We always check rvparkreviews.com first. Critical reading required, sure, but hey, that's true of everything in this connected universe we now live in, isn't it? I look for recent review count, trends and things that matter to me (playground, ease of access, neatness, etc) and go from there.
And I try to always review parks after I stay at them to give back. Great service.
I only had one review edited and that was because I mentioned a SP interpreter by name (in praise at that) -- which I suppose is some sort of no-no.
@NCWriter: we stayed at Tom Sawyer twice in Sept/Oct and didn't have any issues with no response. Bummer. It's a nifty little park, despite the dusty roads and crappy entrance road, we definitely enjoyed our time there (whilst covered in Off insect repellant!)
