Yes. This is mandatory and VERY IMPORTANT. The check-in procedure is done for several reasons. First, this is how we know that you have made it safely to the end of the day and how we keep track of everyone. Second, you must check-in to receive your room assignments for the night. Third, you must check-in to receive the next day’s cue sheet. Although it’s tempting to relax after you’ve made it to the end of each day, you must check-in before you do so.
