To be able to uniquely log into the My Tours website or the R2NSC app, we need a unique e-mail address for each participant. That means that everyone can only book the R2NSC, the RAC and the ORC once. Of course, a person can register multiple participants if he has their contact details and, in particular, their e-mail addresses. Group registrations are, however, not possible for 2018.
If the registration does not work despite of a different email-adress, please log out and later log into the R2NSC-Shop again. Alternatively, you may use another Browser.
