I work in the advertising industry and I can tell you with virtual certainty that information like all of the praise, complaints, ideas and general discussion that makes this site so fun are monitored by someone with HFEC or its marketing/research partners (if they don't handle this in-house). Regardless of how loose our thinking or conversations are here, they are worth their weight in gold to the people making critical decisions at HFEC. This site in its entirety is essentially an ongoing, free focus group providing regular and invaluable customer feedback on every aspect of the park. And while information shared here doesn't necessarily provide a consensus on anything, it does offer a feel for what's keeping, or could continue to keep, the pulse of the park going strong.
I wouldn't be surprised if there are registered members here who work for, or are closely affiliated with HFEC. I say this because in my line of work, we routinely leverage access to forums similar to this one for everything from target insight to nuggets of inspiration for new ideas.
So, folks, the moral of the story is, keep wishing, keep dreaming, keep complaining and keep posting anything on your mind about SDC. I guarantee the powers that be are watching and listening. And there's no such thing as a bad idea.
