Students that have already paid that have become student volunteers can be reimbursed the difference in registration fees.
Every year there are some students that have housing locally, and/or who are coming with their family or sharing a place with other people from their lab. In that case, the SV still have to pay the SV registration fee (approx. $130), but after the conference you will be reimbursed the registration fee. There is no other reimbursement.
The SV registration fee covers the housing. The conference is free, and the housing is a very interesting rate. However, some years the housing is either cheaper or more expensive than planned, we only know that at the end of the conference. As a result, you will either be reimbursed the difference or have to pay the difference, at the end of the conference. Usually, these are relatively small amounts (less than $100)
