The main campground itself at Wylie Park is rather attractive with mature trees and reasonable site spacing (there's a secondary North Campground that's newer with less mature vegetation). Pricing is a little high at $36+/night for FHU, but the reason folks come here is for the park's other amenities including Storybook Land, Wylie Lake, go-carts, bumper boats, mini-golf, etc. This place is a kids' paradise.
Which leads to the situation on weekends: this place is positively overrun with kids. Kids crying, kids riding their bikes through your campsite (and ill-informed adults, too). The geese in the waterfowl pond adjacent to the campground made quite the racket, too, but that didn't bother us. The kids did. Fine if that's your thing, but to a couple of 50-somethings without kids anymore, this was annoying.
Midweek, though, the place was terrific, maybe 50% occupied. Staff was friendly and welcoming.
Great place right next to Storybook Land. Very clean, well laid out, everyone was very nice.
