We were there last Friday, 6-27, and got there at rope drop and followed the crowd to Anna & Elsa. We waited just under 20 minutes to see them, they were in the same room, but across from each other. First we saw Anna and talked to her, and got pics, then we saw Elsa , talked to her and got pics. My youngest 6yo daughter enjoyed it, but not as much as I though she would. We didn't prepare her for it very much, in case the line was going to be unbearable I didn't want to disappoint her, so we didn't tell her about it until rope drop. She liked it, but was a little shell-shocked I think to really appreciate it. It's so hectic getting there and then it's only a couple minutes and bam you're done. Her face was filled with amazement though. My older 11 yo daughter wasn't as impressed, she thought Elsa had a bad wig; it did look kind of funny.
The rest of the day when we passed by the wait seemed to be 90-110 minutes, not nearly as bad as the 180-240 minutes we had heard about in the past month or so. The opening was madness to get there, but maybe some of the mid-day craziness settled down. Although 90 minutes would have been too long for our family to wait.
