This park is fairly close to Yosemite Natl Park but the site are very close together. We made reservations on-line at the KOA site which we have done for several KOA campgrounds but made an error in the departure date by 1 day. After check-in we discovered the error and went to the office to see if we could add the extra night. We were told there was no availability. The staff member was uncooperative and inconsiderate. She was not happy we had made reservations on-line. Also when we checked in we were charged pet fees for cats without asking us first what kind of pets we had; which has occurred at every other KOA campground. There was no cell reception. WIFI access was not available for three days. After the WIFI became available I checked the KOA web site and found there were available sites for the extra night we wanted. Because the camp staff would not assist us with an extra night we did not wish to stay.
