To increase stability and improve the user experience, Gather Space reservations are capped at a maximum capacity of 500 users. Events with more than 500 attendees can absolutely still happen—they will just have to be divided across separate Spaces with portals connecting the separate Spaces.
At this time, if you need a reservation for a 500+ event, please contact us.
Tip: Want a seamless experience for your 500+ event? Work with a Gather Service Partner! Check out our list of approved vendors at https://gather.town/partners.
