Sorry I don't have any "Get to 60 in 3 days" pointers. I don't know of any secret areas that give double xp that no one else knows about.
No, I'm talking about a different kind of sweet spot. Those times where you can get to certain areas fast, pick up a bunch of quests do them quickly and gain several bars easily.
My hunter was getting close to 50 and these three spots helped alot:
*Western Plaguelands - You fly to Chillwind Camp, travel and get a quest to travel an extremely short distance - Sorrow Hill - to kill some skellies and ghouls. I also paid a visit to Felstone (?) Field to get a key, luckily a mage 2 shot the mob I needed, but I'm going to wait a bit yet to go back to that area.
*Blasted Lands - You can fly to Nethergarde, travel a short distance to the Blood Elves and do about 4 hunting quests (and the imperfect draenythst quest too) all in that general area.
*Searing Gorge - You can fly to Thorium Pt, pick up quests right near the gryphon master and do 3-4 hunting quests right below the flight path.
Doing this enabled me to hit 51 painlessly. Hitting a new level always send me to the Auction House (I will not have enough gold to get an epic mount due to impulse shopping habits!) and I found 2 nice bows for sale. I could'nt gauge which was the better, so I did a search for some of the more well known hunters on our realm and asked one for advice. I mentioned my level and he said don't bother with those bows on the AH, instead acquire the AV quest reward bow. A better bow, essentially free?!?!? I'm in!
In a moment of serendipity - I was pleasantly surprised to find out being level 51 allowed me to enter Alterac Valley (pvp). I hadn't really done much pvping on my hunter and it was far from my mind - giving the bad feelings pvp gave me on my priest. Of course my level 51 hunter was no threat to the horde, but I wasn't there to actually pvp anyway.
You can pickup about 5-6 quests outside the entrance and doing several of them, in addition to getting xp for 3 winning tokens took me 1/2 way into 51! Not bad, not bad at all. This is the type of stuff you miss once you're 60.
Bitten off more than I can chew
