Don't plan to get to the Bar your first half-dozen or so runs.
Step 1.) Clear your day's scheduleStep 2.) Waste all day in BRD
Make sure you group with people with the same goal, most runs aren't full clears.
Ah, BRD, probably the best dungeon ever created in WoW. And I genuinely mean that, it's not hyperbole. There's so much to see and explore and it's incredibly well structured. Back in the day a lot of people disliked it, but a lot of people also didn't realize that the dungeon wasn't meant to be done all at once. It was two dungeons in one, and the extended level range and the "checkpoint" of acquiring the Shadowforge key reinforced that.
A group of friends and I meet up every Friday for a number of months late in Vanilla to full clear BRD. With us knowing the place perfectly, and seriously over gearing the place (though I only actively raided at the time) it was at least a 3-4 hour run every week.And we loved every minute of it each time.
