Well see, that's more of an interesting offer.. if Uni is trying to make it an events hosting setup.. that makes far more sense than trying to grab rando off I-drive and convince them to goto a Celestial park restaurant.
The events model allows them to target specific planners.. and also gives Uni the chance to potentially charge the conventions for access/marketing.
Think 'team dinner' etc.. sponsor parties.. etc. Becomes another arrow in Uni's quiver of event offers.
It also gives them an immediate on-ramp to sell 'after 4' style passes to those audiences.
The pitch from Uni to these companies/planners would be like..
Tier 0: You offer people this wonderful unique experience to wander, shop, eat, and drink! See our nightime entertainment and be merry!
Tier 1: You offer the same, but offer to host company sponsored events at the resturants or bar.. either organized meals or social hours, etc. "MACK Cosmetics Vendor Appreciation Event"
Tier 2: You offer to sell the companies 'after 4' passes they can buy and offer to employees or guests.. so people get opportunity for meals, rides, and entertainment
Tier 3: You offer to rent out an entire land for a function
Tier 4: You offer to rent out the entire park for a function - but now you don't necessarily have to exclude your own Helios and other UNI guests from Celestrial Park
UNI has been doing such things for ages.. but now Epic and CP can be experiences they can offer in more tailored packages.. making them more mauluable to the customer's needs.
But all of this really hinges on... CAPACITY

Having nightly entertainment in the park will help sweeten the deal, because as just a dining/bar venue.. it's still pretty weak on its own.
