2017 classes run from May 31 – August 30. Advanced registration is required for all classes. 24 hour cancellation policy applies for all classes. Clients are responsible for watching ROI social media pages or this page/ website for weather and class updates. In the event of in-climate weather or other external complications beyond our control we will try to move classes into the studio (with first priority for attendance in studio going to our regular members), this is not a guaranteed option. In the event class is cancelled or the number of participants to move into the studio exceed the maximum number permitted for the space and one is not able to attend, the client would not be charged for that days session. Class may be cancelled if only 1 participant is registered. Grant Park class packages and summer passes are for the classes schedule as “outdoor classes”, listed on this page, only and are not to be used for any of our regular in studio small group classes or otherwise. Refunds will not be given at the end of the session series for any unused sessions. Refunds will not be given in part or in whole for summer passes. Summer passes are non transferable. Summer passes are only good for one season and do not transfer to the next year.
