Protip to winning Royal Menagerie:

Queue up as close to JP Midnight as you can (11AM EST, 10AM CST, 9AM MST, 8AM PST). Might want to wait 15-20 minutes after.

When you do this, you're going to end up with more people who are there doing roulettes. These people are usually overgeared for the instance and/or experienced. If you, the newbie gets stuck in with 7 veterans, you are 90% sure to succeed within an attempt or two unless you're one of the tanks or healers. And even then, it should be easy. That's how I got my OT clear for the first time.

The later in the day you wait to do it, the more chances there will be of you getting other newbies trying to clear. More newbies = more chances of mistakes being made = more wipes.
