It's always safest to check each level of the variable...
<cfif StructKeyExists(Request, 'EventId')
AND StructKeyExists(Session,'eventID#Request.EventId#')
AND StructKeyExists(Session['eventID#Request.EventId#'], 'registration')
AND StructKeyExists(Session['eventID#Request.EventId#'].registration,
'groupBookingID')
