Of course. Here's an example of bad luck.
Space Mountain people are mean. We took the AWESOMEST picture ever, but we didn't take a picture of the screen because we were going to buy it anyway. When we go buy the picture, the guy tells is it's blocked and that killed our day. We then try again the next day and they close right when we get there. We try again a few hours later and the same thing happens. We decide to eat and it opens up again the moment we sit down. After that, we walk by and the lady says it's closing in seven minutes. We decided to just park hop and my friends texts us saying that Space Mountain just opened up again. I swear...they're like spying on us or something!
