From one Niki to another, just ignore the jibes of those who don't know what they are missing by skipping the parks. I love the parks, but I have gone many times and not stepped foot in a single theme park. As
DVC owners it can be easier to go to WDW and do other things than worry about making an exchange through RCI or paying OOP for another vacation destination. Kudos to you for trying the non-traditional activities. You will have a blast.
I have done all of the above activities, and all are great. I am into sports as well, so visiting ESPN and Wide World of Sports have alot of stuff to do. Regular golf, as well as mini-golf are great. Oak Trail is very beginner friendly to try it out with your 7 year old for the first time.
I also love to shop. You can get some really great shopping, Disney and otherwise, at the Premium Outlet Mall. The Disney outlet is awesome, and you can snag some really great deals at Coach, Liz Claibourne, Bass, Nike, Osh Gosh, Gourmet Store and many others. If you are not into the outlets, there is a Big Mall right off the expressway.
This trip is for you and your family. Just have lotsa fun.
