I believe you have to break the automagic HABTM relationship into hasMany and belongsTo with an explicit model representing the join table - manually join your Event and Guest models to the EventGuest through those relationships. The issue is that any time HABTM relationships get updated, the rows in the join table will get re- written without your data. It's not as big of a pain as it might sound.
