I have an opportunity to attend a conference and get a great rate at the GF in June 2021. I was aware of the park reservation system but had not been tracking availability. So for the dates I would go, no Park Res are available for any of 9 days for HS. Several days either MK and or AK are not available. I know about Park Hopping after 2pm.
How can Disney sale rooms or tickets with this kind of limitations? What am I missing?
