Tourism is tacky by its very nature. I am not sure it can really exist in any other form. If you are building something deliberately for tourists than tacky is going to happen. However, I think there are lines that folks need to be aware of when you are planning and building such a destination. The first thing you need to understand is that it really isn't that important that your tourist trap represent reality. It is a fine line between ye olde tourist trappe and weirding people out. In the end, just embrace the tacky and let people revel in it.
