I have no data, but I have to imagine the pre- and post-parties with gated garden views are way more popular than the seats & sweets option. The view of the show from the Terrace itself is pretty bad. And as stated, it’s not like you couldn’t just have a wall of windows there, which would probably sell better than seats & sweets with genuine table service. The other options don’t really have any reason why they need to be in the Terrace since they’re just a few tables of (subpar) desserts that people blast through either before or after the fireworks.
