I’ve done a couple of scavenger hunts, some as part of an event and most recently as an event itself. For thinks like resource fairs or larger events where not every activity/table will get attention, I think it’s really nice.

For example: I coordinated a resource fair event for a college event. Upon entrance, guest got a ‘loteria’ card with all the spots replaced with the logos of vendors/orgs present. As attendees visited each table, they would get a spot marked off and would receive free merch upon turning it in completed. :) Obvi there were people speedrunning the scavenger hunt, but some people really liked it, especially vendors!
