The view of Illuminations is good from the outside deck and from window seats closer to the courtyard corner (right side). There are trees that block the view on the left.
Additionally, the arch in the water creates a partial obstruction, in that it partially obstructs views of the video globe and inferno barge.
Every time I’ve eaten there and have still been dining at 9 PM, I have gotten up from the table and gone outside. I’d probably do that even if I had a window seat.
I want the full effect from fireworks, not just the visual and muted sound. I need to see, feel, hear, and even smell fireworks.
And no, there is no outside seating.
