This waterfall, located in the Valley of Wisdom in Orgrimmar, is an ideal backdrop for a lovely wedding. For added flavor, give everyone in the wedding party waterwalking as a unique touch.
This lonely, rose-strewn arch in eastern Gilneas sits high isolated high atop a hill. The perpetual rain and gloomy atmosphere make this a pretty unique wedding locale.

Tucked away in the center of Duskwood, the Twilight Grove is an idyllic forest hidden in the center of an otherwise dark and forboding zone. There are several locations perfect for a wedding, like the one pictured here that stands just west of the Dream Portal.

The Twilight Grove also features a moonwell that makes another picturesque wedding location.
Darnassus has several lovely and out of the way spots for a wedding. The alcove pictured here is one of two towers flanking the Temple of the Moon -- this is the western building. As a warning, there is an NPC that patrols in and out of the building -- however, she stays off to the side while she is there.

This private area is actually perched above the main gates into Darnassus from the rest of Teldrassil. It can fit many people, and the riser on the Darnassus side of the gate is a good stage for a wedding ceremony.

This gazebo is in the heart of Stormwind, added with Stormwind's makeover in Cataclysm. Located just behind Stormwind Cathedral, it was tailor-made for a roleplay wedding. If you're looking for traditional style, Stormwind is the way to go.

If, on the other hand, you're looking for something a little more exotic, try flying into Zul'Gurub. If you fly over the wall instead of entering through the zone portal, there are plenty of empty temple buildings and other great potential wedding locations.
