Do I need a ship, a zeppelin or the tram?

No. The way is over land, or by flight path.

Can Alliance players make this trip?

Yes, in about 32 min on foot. Horde territory: guards and players will attack you. Timbermaw furbolgs in the tunnels attack until you earn reputation with them. Most players just run through.

Are these times exact?

They are estimates, give or take a quarter: flight times come from real Classic flights, walking times from the real size of each zone, and ships and zeppelins count up to five minutes of waiting.
