The Functions Module in EventsAir lets you create an unlimited number of functions, such as dinners, tours, and any other activities where you want attendees to register in advance, and possibly pay a fee to attend. Functions are usually included in your event agenda, and you can also limit the inventory (number of places available).

You also need to consider how you'll manage guests (such as partners of attendees, or colleagues), since guests can be active participants in your overall event, or may only join the main attendee for just one function.
