Just returned from 2 week trip & tried this 3 times.
1st time 9/28 was about 15 minute wait & all the pictures were great - 2 characters.
2nd time 9/29, the wait was so long that the CM wouldn't even let us wait there, said to return in 20 minutes to check if things quieted down. She said she had never seen so many people there before. We had an ADR, so didn't return.
3rd time 10/4, wait was about 20 minutes - 3 characters, but the photographer was terrible. There wasn't a single picture that turned out - we had 5 in our group that day & in each picture someone wasn't shown & he never said anything about moving so he could see everyone. The CM at the camera shop said she'd never seen a set so bad before & offered to send us back to try again, but we didn't have time.
