A few tricks to break up the tedium of that final stretch include: explore new areas and quests; pick a faction (such as the Timbermaw or Argent Dawn) and grind reputation, focusing on that rather than your level; spend some time in PvP, which has a small experience reward; try farming for money or drops instead of xp; and do some instances. You could also concentrate on your tradeskills if you've been neglecting them.
Of course, nothing really changes the fact that it does take a while to level, and if you haven't the stomach for grinding, you may get bored. I've found breaking up grinding with some PvP works well, and I also used the WoWVid player for a while to entertain me through the killing. Have you any tips to make the home stretch go by quicker?
