If there is a local festival whose name is "Noun + Festival" like "Sunshine Festival," is the name of the festival regarded as a proper noun?
I go to Sunshine Festival every year, which is held in my town.

I thought #1 was correct because "Sunshine Festival" seemed to be a proper noun. But I find many "the * Festival" in English corpus - for example, the Ravinia Festival. "Ravinia" seems to be a place name, and if so, I think, it should be a proper name.
Or is it a person's name? I understand I should put "the" before "Bach Festival" because literary there could be many different Bach Festivals if you don't put "the" before that.
