I think the important thing to remember here is that there is no right or wrong answer. As long as whatever you are doing is not against the rules, or specifically bothering someone else, or somehow impacting someone else's fun, then whatever someone wants to do in the parks is their choice and their business. Many people -- as a lot of us have stated in this thread -- love taking photos and couldn't do without them. That doesn't mean that we are enjoying our time at DLR any less than anyone else, or that we are not experiencing the magic, or not having a fantastic time because we are looking through a lens. It just means we are enjoying the parks differently than those who choose not to take a lot of photos, and we want to have photos for specific reasons (memories, crafts, projects, etc.).
As the saying goes, vive la différence!
