It is certainly best if you register for everything at the same time as the on-line form takes you through the process in one sweep. You cannot return to the form at a later date and add housing.
If, for some reason you are unable to sign up for housing when you register, you will have to call the registration team and make arrangements with them. I definitely do not want to encourage people to do this though.
Please be sure to check out the new postings at https://www.conf.gnsi.org/program/ <https://www.conf.gnsi.org/program/> . You’ll find information about the outstanding keynotes speakers plus a listing and descriptions of the exciting mini-workshops, workshops, and field trips. Also, look over the partial list of the Core Conference presentations – we still have more to add!
Looking forward to seeing you in Boulder!
