I have a question about the registration process. When I registered the directions said there is a $100 dollar charge for an extra person not bringing a car. I added the $100 in my total, but did not understand how to add them to the daily roster. Is it a $100 a day or a $100 for the week? When I selected the $100 option for each day it tried to add a $100 dollars a day. Just asking to clarify the registration process.
