Our Activity Officers take their responsibilities seriously and if an officer believes in his/her judgment that you should not participate in an activity, before your departure, even if you pass your medical, he/she may exclude you from the trip. In this circumstance, you will be offered the option of taking another trip considered suitable for you. If during an activity the activity officer considers you should not participate further he/she may direct you not to continue and you must follow their instructions for your own safety.
