My five went from 68 to 71 just doing all the quests* in the Borean Tundra plus they got at least 600 gold each. I can now go and do all of the Howling Fjord should I wish, or move into Dragonblight. My toons were rested the whole time which might explain that.

*5 quests to go (I'm not going to pay 350gold for 5xOVERCHARGED capacitors) plus 4 Nexus dungeon quests. I'd say there are about 140 odd quests for Alliance in the Borean Tundra. I got the achievement for 130 BT quests and I was still going with more... [s](wowhead only lists about 153 for alliance?)[/s]

Edit: * no idea what I was thinking about that day ... I think I had done too many quest
