We stayed at a cabin toward the end of the park. The cabins are great and super comfortable and the bathrooms are clean. Saw park staff cleaning and taking out the trash frequently. It is about 10 feet from the highway so loud all day/night.  Interesting history but the springs themselves have mostly been paved over by 84.  Hiking trails a bit confusing and mostly gas line right of ways.  Would recommend if you need a comfortable place to stay on a road trip but not exactly a "camping" getaway.
