Thank you for the information. Yes, late September early October we'll be there. Showcase Citrus sounds neat. We are staying right near WDW property, so that is a quick drive. However, while it seems like there is a lot to do there the orange picking seems to generally start in November as per their website. Maybe not a big deal to some, but up here in Canada there are no orange trees and my kids would love seeing that.
Different types of oranges become available at different points in the season, so maybe there will be at least some parts of the grove that will be open for picking when you're there. Enjoy!
