Kflex and Jaik are on the right track. The bonus exp from your hunting log(if you havent done it yet) will help. The +30% exp ring will help. When you que for the dungeon, do you directly hit the Halatali option? Often ques go faster if you give the system a couple options to go with. You would get a little less exp in copperbell or tam tara, but if it means getting in instead of waiting thats still a win. Im pretty sure you should have access to the leveling roulette by your level. That one gives a pretty good bonus once a day. You could try queing for the guildhests too. And while it isnt much, try to keep some cheap food in your inventory while youre leveling(theres a merchant in every town who sells some for pocket change, no need to use the board) and eat it for the extra 3%.
