Just got home, out for 15 nights, 3500 miles, with the GD. Stayed in KOAs all the way.
New to us, as we usually go state park or forest service CG's.
For camping with the GD I really liked them. Pools and playgrounds were a big hit with the kid. Staff was always friendly. Many had some sort of other kid thing going on as well. Wifi was pretty good at all campgrounds
As we don't reserve more than a day ahead (just the way we travel) I found it very nice to be able to log on to their website and make a reservation for the next day.
Locations were very close to the things we wanted to see.
Seemed like they averaged about $45 a night. So for us, with the kid, I thought KOA's were a pretty decent deal, and very user friendly, as far as making reservations, staff etc.
So would be pretty hard to us to complain about our experience with them
