My family and I we went on the 16th and they were making all the cars make a line and wait for like 30 minutes in order to keep going toward glacier point because it was full and then there were people who didn't want to wait in line and decided to turn back. Also after the wait, we were on our way there we saw control fires and firefighters monitoring the fires. Nothing dangerous because it was a control fire but I don't know if that might be the reason why they didn't let you continue
There's limited parking and there was an active fire too. We waited for an hour and then went to glacier point.
