AIHce EXP Full Conference (on-site and virtual) refunds are subject to a $150 USD processing fee. One-Day (on-site and virtual), Expo Only (on-site), and all PDCs (on-site and virtual) registrations are subject to a $75 USD processing fee each.

  • To receive a full refund (less processing fees), cancellations must be received on or before April 16, 2021 (5:00 p.m. ET).
  • A 50 percent refund (less processing fees) will be processed if request is received between April 17 and May 5, 2021.
  • No refunds will be processed for requests received on or after May 6, 2021 or for no shows.

Tickets to Technical Tours and AIHF Pin and Virtual Fun Run/Walk purchases are non-refundable. Refunds will be issued approximately 2 weeks post-conference.

Transfer of Registration Type 

We understand that your ability to attend AIHce EXP physically or virtually may change after you register, and we have designed a flexible registration system to allow a switch from an in-person registration to a virtual one or vice versa. To switch your registration type, submit your request in writing via email. Note: switching from in-person to virtual participation may require a change in selections of PDCs or other non-virtual activities.


Substitution of a registered AIHce EXP attendee by a business colleague will be accepted. A $50 processing fee will apply to all substitutions if notified in writing via email by May 5, 2021 (5:00 p.m. ET). The new registrant must be named in the written notification and must register before the original registrant is refunded. If the original registrant was registered as a member, the new registrant must also be a member or join membership upon registering or pay the balance due for a nonmember registration. Beginning May 6, 2021, no substitutions will be allowed, and all requests will be treated as full cancellation or the original registration subject to the cancellation processing fees above. The new registrant must register as a new attendee to complete the registration and housing.
