So I'm trying to figure out my ADRs that I want to make. We are traveling on October 4th. How can I plan on where to make my ADR for the day when I don't even know which park I'll have extended hours or which day the Mickey Halloween parade will be? I'd like to do the least amount of park hopping. I can make my ADRs on April 7. Will they release the extended hour times and the Halloween parade before then?
