can someone explain the difference between A Campground and A RV Park?
This is certainly an unofficial answer, but I think most people consider a campground to be in a more rustic, natural setting. They normally allow tents and camp fires and may not have many amenities such as swimming pools, cable TV, and Wi-FI. RV parks tend to be more manicured with concrete pads, and many amenities including pools, spas, cable TV, Wi-Fi, exercise rooms, clubs, etc. Many parks do not allow tents, and many do not allow fires. Course it is not unusual to find lots of places that hit in the middle of these two descriptions so it is difficult to know what to call them.
You did not mention it, but I think there is another category--RV resort. Basically I see a resort as being a full service park. They should provide very large, landscaped sites, full hook-ups, and numerous amenities. I think this term is used too loosely, but hey, I don't name the places.
At best there is probably a fairly thin line between these three types of places, and I don't think you can expect to find one particular atmosphere based on just the name. That is why reviews should thoroughly describe the place so that others get an idea of its "looks" and accommodations.
