In order to appear in venue search, you must add at least one rentable space to your venue.
You can do this under the Rentable Spaces tab, where you'll be able to upload photos, capacities, floor plans and more for your space(s).
So, whether your venue has one room or 100, you can details your offerings here. When a user searches for a venue based on capacity, vibe, or another factor, your venue will appear as a result if one of your spaces matches their search.
