We stayed here in May 2019 in a car with a roof top tent (tepui). Since it was early in the season the campground was pretty empty. The sites by the river are nice for the river noise to fall asleep too, but as we later found out they also flood when it rains. Overall, I think this is a good alternative if you can't get any camping in the park. Pros:

• Available when Yosemite National Park isn't
• Close to the park
• Has wifi and hot showers

Cons:

• Expensive
• Bathrooms could use some work
