How long is the wait to get onto the course? Is it crowded on Sundays?

Afternoon is about 10-25 minutes

Sometimes the wait can be between 5 - 30 minutes to get on the course. Depending on how crowded the mall is that day, it can be fast or slow. When the climb does get busy for example when the harnesses and/or slings run out employees will give a hour to each customer that goes on by writing what time they get on the climb on the wrist bands. Then then the employees on the course will check from time to time on customer who have been on the course for more than an hour and show them the way out. As for it being crowded on Sundays, Yes it can get very crowded. Recommended to arrive early but the climb doesn't open until 11 am and you cannot purchase tickets early.
