The group does not provide any form of insurance for the Hemel trip for anyone attending.
You may wish to take out a policy to protect yourself in the event the trip cannot go ahead due to unforeseen circumstances - like the hotel or Snow Centre being unavailable, or if you are unable to make it due to ill health or family emergencies.
Warning
To make it clear; the group will not be able to refund any payments made if the Snow Centre or hotel are unavailable.
