Yes, someone who has registered who selected not attending the reception and/or banquet can change their selection and indicate they will attend at a later date by going in and modifying their existing registration. However, since we need to commit to numbers for both events prior to the conference, this must be done at least a week before the start of the symposium. Further, if one is bringing a guest, guest tickets for either or both events can be added to any registration by modification. Note that guest tickets can also be added to an existing registration. If added and paid for after April 19, the cost will be charged at the higher Late Registration fee. Further, if guest tickets were added prior to April 19, but unpaid by April 19, the fee due will update to the Late Registration fee as well.
