Hello WedinDis,
Unless you have a hankering to watch Men's soccer or Women's Fastpitch softball, there is no real reason to go to Wide World of Sports. (Both of those events will be going on during your stay.)
There is an All Star Cafe' there and a Disney sports themed gift shop. These are both accessible and free to every visitor.
The Wide World of Sports is a great complex! Very "Disneyfied" - great landscaping and attention to detail, etc. However, it is designed to be a venue for many different sports activities and it does attract a great crowd for those participating in the events. But, if you do not have a vested interest in the events there is no reason to go. With the exception of the following:
It is the spring training home of the Atlanta Braves.
The World Champion Tampa Bay Buccaneers have held their summer camp at Wide World of Sports complex the past two summers.
And, it was home to the AA Orlando Rays minor league team! (the team is moving to Montgomery, Alabama next year.)
That being said - I love the complex. Went to several Rays games and to see the Bucs practice. But, none of that will be going on while you're there. So it is probably something you can skip.
Hope this helps!
