Large Space Lottery for UW-Madison Student Groups - Fall 2026

Reserve Space for Fall 2026 Events

The Registered Student Organization (RSO) Lottery is the event where RSOs can enter to reserve a Wisconsin Union large room space on a Thursday through Sunday. These large spaces can accommodate a dance or social event. 

Space lottery tickets will be given to representatives from each group who signs up at the event, and then groups will be called in the order in which tickets are chosen. When a group is chosen, they can pick from a list of available dates. When a group picks a date, it is entered by an event planner and we move on to the next group until all available dates are filled or we run out of groups.

The group representative will be the main contact for the reservation and should come prepared to provide contact information, and with dates that will work in mind. Groups may only receive up to one date.

Good luck!

Additional details:

• No advance reservation is required for RSOs to attend the lottery.
• Lottery registration will be held in the National Panhellenic Council Room from 4-5 pm. We will begin drawing tickets promptly at 5 pm. Any group arriving after 5 pm may have the opportunity to book space only if spaces are available, after every group who arrived to register has had the opportunity to book.
• Registered Student Organization (RSO) status will be confirmed in WIN on the evening of the lottery. Groups who are not in active status in WIN will not be permitted to reserve space that evening and will need to confirm their status through Center for Leadership & Involvement (CfLI) prior to being permitted to reserve space.
• This lottery is for social events for 50 people or more in Great Hall (Memorial Union), Tripp Commons (Memorial Union), or sections of Varsity Hall (Union South) on Thursdays, Fridays, Saturdays, and Sundays.
• Groups will only be booking a date during the lottery. Additional information on planning their event will be provided via email following the lottery.
