I put little stock in cg reviews, I do at times read them but do not use them to make any decisions. The guy that writes the cg was his idea of heaven, well it may have been just an ordinary cg with a small pool, not much for the kids to do..... But to him it was the perfect spot cause his site was nice and the weather was perfect and he was probably a pretty laid back guy.
The guy that writes the bad review may have had a great site but the weather was so so and kids everywhere. Maybe he's wound a little too tight, every little thing bothers him and he writes the place was terrible when in fact it was a nice cg.
Like the op said one guy will swear by that cg and the other would never go back. I guess if you see a long pattern in the review then maybe your on to something.
