I usually move to Scholomance around that level but it really depends which high lvl toons you got available.
With my Furry Warrior I do the first three rooms and then reset the instance which takes me about 20 minutes and gives about 25%-30% XP/lvl if I recall that correctly.
If you do the Herald you get at least one Large Brilliant Shard which sells quite nice too, not counting the Runecloth.

Being Alliance the flightpath at Aerie Peak is just great since taking the slope through the mountains takes only about 5min to get to Scholo.
