Well Stormwind is about as big as cities get really. You can catch the tram from there to Ironforge (entrance to tram is in the Dwarven district). If you're playing on a trial account, its unlikely to feel very busy cos I don't think you can talk in trade and general which are the 2 main channels in the city - but you should get a feel for how busy your server is by how many other players there are milling about the Auction House and bank in Stormwind (centre of the Trade district).
While it is a big city, it is also rather deserted.
Ironforge is where everyone is, you will be sent there eventually don't worry about it.
Wife a bit annoyed by the time I went to bed. 

Human Priest - I think I'm in Stormwind at the moment.
