Sports on offer Group lessons and open hours 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). Reservation procedure For all the group lessons and open hours you need to make a reservation beforehand. You can make a reservation through the website or the My ACLO Sports app. When you arrive at the Sports Center, you need to confirm your reservation by scanning a QR code. You can do this with the ACLO Access control app. At every sport location there are multiple QR codes, if you have a reservation for hall 1 then you need to scan the QR code at hall 1. If you get a green light after scanning the QR code, your reservation is confirmed. Please note: because there is a limited number of places due to the corona measures, you can currently have a maximum of 3 reservations. On the day itself you can still make a ‘last minute’ reservation if there is still room. Cancelling a reservation You can cancel up to 2 hours before the group lesson or open hour starts. If you cancel too late or do not show up, you will receive a warning the first two times. After this your card will be blocked if you are late or do not show up. Your card can be unblocked when a contribution of €10 is paid at the service desk of the ACLO Sports center. If you are too late to cancel, but you are not feeling well and/or have COVID-19 symptoms. Please stay at home and contact the Executive Board of the ACLO. Locations The group lessons and open hours are held at different locations: the Sports Center and the WAS at Zernike and ACLO Station in the city center. On this page you can find the addresses.
