I basically had the same question, but haven’t seen an answer yet. My limited understanding is that with gold, you still have to get there early because they cap the gold line, and when they do, all the gold members arriving after have to join the regular line. I just don’t know when the gold line usually gets capped. From the sound of it, it seems like being gold doesn’t mean you can get there any later. It just gets you closer to the front if you do manage to get in the gold line before they cap it.
