I don't think this is a repost so appologies if it is.
There is a spot in Wintergrasp which is counted as Icecrown. It is not a large area but easily accessed by ground mount and allows you to mount up on your flyer.
This could save people farming ore time from flying by FP or by hearthing.
The spot is around 84.02, 43.52 and is a small ridge. It will say "Icecrown" when you get there and the world map will default to icecrown.
