What does "また朝までコース" mean?

Question

It's a small hashtag on twitter. https://twitter.com/hashtag/また朝までコース

Does the コース here always refer to a meal? A plan of action? Are they saying they're gonna party till morning?

Answer 1

Yeah. They are saying they're gonna party till morning.

We might say

終電{しゅうでん}逃{のが}したから、朝{あさ}までコース。(カラオケ？)

So, we missed the last train home. Let's party till morning(Karaoke?).

I do not think it always relates to a meal, say drinking beer at Izakaya, but it could be. I might be wrong tough, I think it is a set phrase with the party. I do not say "昼{ひる}までコース。" or something.
