She wanted her husband, Steven, to go on the ride with her.
"It was a long day. I had bronchitis, I had a crying baby and my husband informed me that he doesn't have it in him to ride my favorite ride," Alexander told WSTM, explaining her expression in the photo.
"It was hot and I was getting tired, but she really wanted to go on Splash Mountain and I had promised her earlier that I would go on it with her," her husband said. "At the time I was just beat and I said, 'I don't think I'm going to go on Splash Mountain.' She said, 'Fine, then I'm going to go on by myself."
Jordan Alexander planned to get her husband back in time for the photo op.
"I kind of practiced it the whole way," she said. "And by the time we got to the last drop I didn't know where the camera was and so I just guessed and looked over and took the picture and that was that."
"When she first showed me the photo, I just lost it," Steven Alexander said. "How could you not? I was like, 'Did you coordinate this with them?' Because it was so perfect."
