Campus tours for Admitted Students

I’m a freshmen applicant who was admitted for Computer Science in Fall 2016. When I try to schedule a tour for the college of Science on the CPP website’s tour reservations page no dates seem to be available. Does this mean that all the dates are booked, or is it a problem with the website itself?

I could call to confirm since all tours are this month (April) so they could all be booked.
