I bought an add-on and a full pass at the same time. Can I transfer just the add-on or vice versa?
If the full pass and add-on were purchased at the same time, the whole transaction must be transferred. The system has no way of splitting the two items apart.
Transfer fees apply to full pass purchases, not add-ons.
If you are trying to transfer an add-on, arrive to registration with your transferee and ask for the add-on wristband to be attached to your person.
