It is essential before going on holiday to ensure that you have an adequate holiday insurance cover.
You should make sure that it is relevant to you, and that the policy terms should not include any exclusion clauses that may affect you.
It is a good idea to include all family members who will be travelling together in the one policy. This will avoid the hassle of having to deal with two or more companies in the event of a claim involving all of you. Often, an insurer will offer a lower 'family rate' for such a policy.
