i think that creating a new table to store the events that a member will attend it's the best way..cause in case that you need to save event related data, like assistance, the time of the suscription, delivery of gifts, it's simple as adding fields to the table....also manage and filter a record per member/event, it's way more easy that parse enum fields i think.
