It's really tough when you figure out that that type of stuff is going on. I speak from experience.
I'm hardly an expert here, but I did notice once thing. All your initial reasons for going to the theme park were great. Then I noticed the last one where you talk about how much it will bother your wife, I don't think you should do things to get reactions from her, or because it will bother her. Create the great memories for your kids and you, and don't worry about what she will think.
