My DH, DD, and DS are taking our third trip to WDW in June 2020, and our 180 days threshold is tomorrow. This trip, my DD finally wants to get her princess on at the BBB in MK one day of our trip. I know that reservations open 180 days in advance, but is it 180 days before the first day of your trip (like with an ADR if you're staying onsite) or 180 days until the actual day of the reservation? I feel like this might be a stupid question, but I could see legitimate reasons why it wouldn't work like an ADR. Thank you for any help with my question!
