There is no additional administrative charge for an attendee who needs to switch their attendance from in-person to virtual or vice versa prior to March 9, 2022. The attendee will be either charged or refunded the difference between the two formats.
Switching formats from virtual to in-person will be allowed up until April 1, 2022. The attendee's payment will be updated to the in-person price, but no additional fee will be charged. After April 1, 2022 switching formats will no longer be allowed, however, an attendee can always substitute another colleague to attend in their place by providing written notice to email@example.com.
