What is it? When is it? Where in HS is it?
Sunset Seasons Greetings was discussed last month in the blog http://blog.touringplans.com/2017/09/07/sunset-seasons-greetings-disneys-hollywood-studios/ . It's on Sunset Blvd from Nov 9 to Dec 31, starting about sunset? It doesn't have a set time (like a show) but seems to be more of an ongoing experience, like the Tree of Life awakenings.
