The holiday is here, there's no denying it. And, well, since I completed it on Bellwether the first day, and have almost completed it on two other characters, I believe I know a little about it. If you haven't started or are just getting started, here are some tips for you.
First off, understand that no egg belongs to you. Whether you're spawn camping or circuit running, nothing has your name on it. Coming to terms with this will make the holiday less stressful overall. You still have a week, so there's no point in becoming completely freaked out the first few days.
A handy tip for people missing their female orc: If you know a female human with the Orb of Deception, putting bunny ears on them while they're in disguise counts. Seriously.
If you're going to Un'Goro and you're on a PvP server, take friends. I'm not telling you whether to gank or not, that's your personal preference, but having the muscle to take out any would-be gankers is always preferred.
When you're not being smiled upon by the RNG gods and are having a low drop of special items, collect enough chocolates to buy everything you need before you go purchase. This will help keep your blood pressure down, so there are less chances of buying something, then having it drop.
If you're hated by the goblins, but are going Desolace - Silithus - Tanaris - Thousand Needles - Badlands, remember that the flight path outside of Gadgetzan is controlled by a non-goblin, so as long as you kill the few guards around it, you are still able to fly out of there and up to Theramore to take the boat.
Remember to relax and have some fun with it. It lasts a week, there are no pure RNG achievements, and all it will take is a little time.
