We spent 2 nights at the campground. Booked it 3 days before our trip as they had a cancellation(?).
Pluses: 30 min drive to the Valley; sites are nicey spaced apart; for $20/night better than staying at a hotel.
Negatives: bathrooms are dirty and have no lights (dark even during the mornings); some people don't observe the curfew hours between 10pm-6am and can be very loud and park rangers don't enforce this rule.
Overall, we were lucky to get a space on short notice in Yosemite in the middle of summer. I would only stay again if they have lights in the bathrooms. Our campsite was o.k. (with bench, fire ring, bear box. But we had a sloped lot which makes sleeping a little challenging, plus our noisy neighbors.More
