You have to take the reviews on rv park reviews with a grain of salt. If someone gives a place a 5, 6 or lower and there are 10 others that are rating it as an 8 or 9, then you have to look at it. Unfortunately people who rate are not going to rate the same as you. If you give a park a lower rating because it has 700 sites and unmatched wild children, then you are not doing the other campers any justice. That's not a fair rating assessment of the actual facility itself. The amount of sites should not matter. The actions of campers (unless there are huge problems that the campground is not trying to handle) should not reflect on the campground either. I'm not saying not to mention it, but it's really not fair to give the campground a negative hit for it. Neither should they be hit negatively for not having an amenity, unless they say they do. I'f they don't advertise wifi and you get there and there is no wifi, then that is on you and not the campgrounds fault. Now if they say they have it and you get there and they no longer have it or its not working then yes hit them in the ratings, but also explain why,for others to know.
And as far as the OP goes, I hope when you mean that you like to let your dogs off leash, that you are referring to inside an enclosed fenced in designated dog area. Other wise it's rude to do in an rv park and against most of their rules
