Buses come approximately every 15-20 minutes which isn't often enough for busy June season. Several times the buses were full and no one could get on. Also, we noticed that Park maps had errors on the bus colors. Going to Curry Village was shown both in the green and purple bus color on paper maps and wall diagrams at the bus stop. Be careful when you enter a bus and make sure it is going the way you want. Purple bus went to Curry Village/Happy Isles in June 2022, Green bus is toward Lower Yosemite Falls. Also, due to covid the front of the bus does not open and all people will exit from the middle/rear of the bus and then enter the same way. There were no official lines to stand in to enter a bus and consequently, we noticed some people who were there first at the stop didn't make the bus since they were "pushed" to the back of the mob. The park needs to update all maps and signage, and introduce line areas to stand in to secure position to enter the bus. Parking is challenging, so the buses are needed, but they need to be improved. Yosemite needs to talk with Grand Canyon or Zion on their bus systems and learn from each other.
