How is the 30th of September a “Ghost Town” day with Mickey’s Halloween party going on that day? Also, do they make you leave the park at the 6 pm closing time if you don’t have a ticket to the Halloween Party?

Hello, We’re looking at going to Disney the last week of Sept. We had major issues finding open hotels, almost everything is sold out. Yet every time I check the crowd calendar it says it’s a ghost town, what gives? I’m hoping its a ghost town but was very surprised at the hotel situation.
