Leveling alts

So... I have a question. What would be decent leveling routes with the 5x on Onyxia, minus waiting an hour+ for dungeon queues? I have blood elves and draenei I am looking to level and play on the server, while maybe doing a couple alts on Icecrown for the last couple classes I want to play, and I want to get them to Outlands before I swap the xp gain back to 1x, since I've done vanilla so much on the official server that I wanna enjoy Burning Crusade/Wrath more. I mainly ask if someone knows some routes I could take with my Blood Elves and Draenei to help get to 60 a bit quicker

Go where ever, except the PvP hotspots.

If you want to be efficient, follow some TBC/WotLK leveling guides. If you want a bit more varied experienced, go where you haven't been in a while. Even the few hubs that don't have that many quests are good with higher rates.
