Hi Jill!
Thank you for bringing your question to the Disney Parks Moms Panel!
If you didn't already see it, there is a
calendar of events on the ESPN Wide World of Sports Complex website. You can filter it for your travel dates to see what all will be taking place during your visit.
It really depends on how long your stay is and whether or not you are a big sports fan, as to whether I would recommend a trip to the complex if there aren't any events that interest you. As someone who loves almost all sports, I would want to visit the complex just to see it. The facilities are truly amazing. I have been to many playing fields as a sister, daughter, participant and mom and these are by far the most impressive I've seen. There is also a nice gift shop and a club house restaurant that you can check out while there. I do think you would enjoy the visit.
However, if you aren't there for an extended trip and already have your days full, then I wouldn't consider it a "must-do". My advice would be to save it for your next trip and maybe something that you want to watch will be going on then!
I hope this helps! Please let me know if you have any other questions.
