For the last several years, the parade was at 5:00 in place of the normal parade.  The only difference has been right around Christmas when the parks are open late when the parade has been at 8:00.
Last years Mannheim Steamroller concerts were then afterward at 6:00.  So, it's tough to get a good location for both.  With the parks open until 8:00 those evenings the concerts could get moved to 7:00.
That will at least give you times to start planning around.
