Where are the Illumination Cruises Conducted?

[MarkLem]

Are they on the big lake at the Worlds where they shoot off the show?

Yes,

The boats dock under the bridge on the walk way from World Showcase to the Epcot resorts.

They are technically on the same body of water as the fireworks and video globe, but they don't get any closer than someone standing on the bridge does.
