Two areas where you will see more merge field options for your event emails: 1) within event emails and 2) on event name badges. These new fields are available when selecting Insert Merge Fields in your email editor at locations in your event where emails are sent.

1. Attendee Table/Team Name is available on the Attendees tab when sending emails using Send Email to Registrant, Send Email to Actual Attendees, Sent Event Reminder Email. New email templates created under Setup with a Category of Event will also have this merge field available. 

2. Exhibitor Booth # is available on the Exhibitors tab when sending emails using Send Email to Exhibitors. You can also create email templates that include Exhibitor Booth # if the template Category is Events. At this time, it is not available as a merge field when sending a one-off email to a particular exhibitor (Send Email under the Actions column on a particular Exhibitor).
