Schedules Schedules Group lessons and open hours With an ACLO Card you can participate in group lessons and open hours at the ACLO. You can find the group lessons and open hours in the schedule. The difference between group lessons and open hours is that during the group lessons, the lesson is being given by a sports teacher. During the open hour, the sports teacher only acts as supervisor (like during the open hours climbing, futsal, and swimming). Corona Due to the Corona measures, the group lessons and open hours will look different in the year of 2020-2021. We, as ACLO Sports centre, follow the guidelines by the government concerning a safe exercising environment in Corona times. This means that the maximum number of participants in group lessons is limited and that reservation for your sports activity is mandatory. It’s not possible anymore to walk in without a reservation. Course hours For every course period there are certain deadlines that you have to take in account if you want to participate in a course. These deadlines are not negotiable so stick to these. You can find the deadlines in the scheme below.
