The "taxi system" was guiding me to Orgrimmar. As a druid it told me to teleport to Moonglade and then fly to Orgrimmar. Well, actually its a bit faster to fly to Nordrassil in Mount Hyjal from Moonglade as there are portals there. Just want to make sure you can put it in the guide.
There is also a Stormwind portal same place for alliance.
