What fits in Grand Ballroom
With a 3.1 m ceiling, a flown wall of Absen PL2.5 Plus V2 (2.5 mm) runs 68 tiles wide by 2 high (136 tiles, 34 x 1 m, 13600 x 400 px) once you keep 1.5 m of trim under the bottom edge. That wall weighs about 1,061 kg and draws up to 21.8 kW (105 A at 208 V). Floor space after a 12 x 7 m stage seats roughly 3,941 theater, 1,612 banquet, or 1,108 classroom. The previz lets you move the wall, change the tile, and check sightlines from the back row.

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.
Planning notes
No rigging point data is published for this venue yet; plan on ground-supported LED or ask the venue for its rigging plot. 5 of the 5 rooms sit under 3.5 m, which rules out flown LED there and limits ground-stacked walls to about 6 rows of 500 mm tile.
Data source
