We went this past Thanksgiving and the times changed closer to the time. MK had a lot of early openings at 7 am or 8 am and stayed open until 12 am, 1 am, or 2 am. Not sure if that will change now that they have the EMM. AK had some early openings as well. There is no MVMCP that week. The last one is the Friday before and then it doesn't happen again until the Sun after. The FOF parade was held at 3 pm and the MSEP I believe was twice a night. I think there were 2 castle lightings. At Epcot the CP and Holidays Around the World begin on Black Friday. Not sure what they will do at DHS now that they don't have the Osbourne Lights. AK did not have anything since they got rid of the parade and now they have new stuff so not sure what the schedule will be like there. What are your dates and where are you staying?
Very glad to read your answer, CynBeth. We're going for just one day during that time frame and want to make the maximize our time. I was looking at https://disneyworld.disney.go.com and seeing that the park hours were closing at 10 pm at the latest! My!!!
