We have done Star several times. If you are hosting a party of this size, there is going to require a separate fee. This is considered a private event. Even to do a smaller party and to have a bartender in suite there is a fee. It won’t be nearly as much as renting the restaurant. But it has to go through food and beverage. We did something similar were quoted prices starting at $500. Another Star guest on our sailing hosted a wedding on their balcony with food and the such. As a Star guest you are basically paying for the staffing. But you can inquire about cost before hand with your genie after first contact.
