At key times some sessions can become crowded such as in January and February just after the new membership year begins. If the lead coach for the session believes that the health and safety of members could be at risk they can limit access to the session. This will be done on a first come first served basis combined with appropriate attendance (e.g. advanced swimmers would be turned away from novice swim session). It is rare that this situation occurs but if it does please respect the decision of the coach.
