If your event lasts more than one day and you want to offer a ticket for all or some of the days you will have to do the following:
Firstly, you need to add an event with a pricelist that will specify the prices for a daily ticket or day-pass. Then you can add the marketing material and publish it when you are ready. You can see the steps here.
For a multi-day ticket you will need to create a new event with a similar title, as:
2-day ticket - event title
2 Day Pass - event title
Full Pass - event title
In this event you'll be adding only one event using a new pricelist with the price of the multi-day ticket and the name you decide for the ticket, i.e. 2 Day Ticket.
Addionally, during the process of adding this event, you set as start date the first day of your event. Then you will need to adjust the wordings that will appear online and on the tickets:
You go to the ''existing events'' tab of your multi-day event
Select the event and click on "alt. date / time shown online"
On the pop-up, select the "custom date text" and enter the dates that the multi-day ticket will be valid for.
In this play you do not add any marketing material.
In order for the multi-day ticket to appear alongside your day tickets you need to follow this procedure:
Initially, you will define the original event as a page of multiple events, through the marketing material by clicking on "Is a page of multiple events" field. See the process here:
Afterwards go to the "festival" column, click on "edit" and from the drop-down menu to the right select the festival you have previously set, to add the multi-day ticket
On the pop-up window choose the event with the Multi-day ticket and hit save. See the process here:
