I have no issue with the club itself coming to WDW. The Magic Kingdom location? No issues from me, it's out of the way and utilizing space that doesn't take away from any real expansion. Same for Epcot and DHS. Both used spaces that I have no problem with them using.
I just took issue if they're building something on an expansion plot that most guests won't ever get a chance to experience. That's all. It's not about harming the guest experience, technically, or about not liking they're coming.
