Yes, this is a half-sized pad with a narrow width.
I'm guessing it will be a patio for more outdoor seating.
I've advocated for every unused pad to be fronted by a festival booth and/or seating to get them away from the lakeside in order that they don't take away the view from the lagoon/fireworks and stop being chokepoints.
When Dan was VP of epcot this was also his mandate. He hated the clutter on the promenade and wanted as many things along the waterfront moved into the pavilions. I feel the worst culprit right now is China, their waterfront is almost entirely taken up by kiosks. Also having all these kiosks (im talking the non festival ones now) along the promenade starts to discourage guests from actually going into the showcases to explore them leading to the "there’s nothing to do here" complaint.
