Our original plan was to stay in Mammoth Cave National Park's campground with no hook-ups, but ultimately we got scared off by the threat of cold temperatures in early April (and it was below freezing one night that we were there) and how unequipped we are for dry camping and went in the opposite direction with our first stay at a Jellystone. The campground was big and busy and bustling with people and activity, but it quieted down at night and everything was well run and tidy. Location is very convenient to the National Park....it's on the same road as the entrance and maybe a 15 minute drive to the Visitor Center. We reserved a full hook up site, but they called us when we were on our way there to tell us there was a problem with our reserved site and offered us a W/E with a 25% discount instead, which was fine (price given is the W/E non-discounted price). Wi-fi wasn't very reliable, but our T-mobile signal was pretty good. Sites are gravel; mostly pull-throughs that we saw. It's a hilly area and most of the sites will require some work to get level. Decent separation between the sites; we had a grassy area with a fire ring and a picnic table. Bathhouses clean and modern. We were there on a weekend, and there were non-stop activities scheduled. Outdoor movies, hay rides, coloring contests, karaoke....we didn't have a lot of time, so we mostly went to the NP, but we did fit in a few things. There's mini-golf, two pools, a waterslide (not open yet when we went, but the heated pool was), a big camp store with a restaurant area, nice playground and pavilion. Not really our style of campground, but it was fun for a couple of days anyway.
