It says you close at 5 PM, but I booked a 3 PM time slot. Will I have enough time to complete the course?

Our customer service hours, which is when we answer phones and reply to emails, are from 9 AM to 5 PM. These hours do not apply to when the courses are operational. We would not offer later time slots to book if there was not a good opportunity to complete the courses. There are no set times for when we close the courses each day, so we give each group plenty of time to complete the courses. However, we must have all guests off of the courses by sunset.
