We are members of a travel group and have used this site to evaluate RV parks against some other sources that also rate facilities. It would be helpful for those who might be planning a group activity if there was an indication that group facilities exist. (just as there is a family friendly line item) Family reunions, travel groups, etc, would find this a big help in choosing a campground for their group activity, in my opinion.
This sort of thing is usually covered in the campground's website. I might be different than most folks. but I normally do not notice this type of thing when staying at a campground. I will in the future try to mention facaulities when we happen to see them. Usually photos of rally areas are included in a campground's website. Good Luck.
