Book at least 7 days in advance to take advantage of the special Advance Purchase rate and receive up to 10% off the best available rate. A full non-refundable payment required at time of reservation. This rate cannot be cancelled or changed once reserved. As an offshore destination, air and ferry services are occasionally affected by adverse weather conditions - in such instances the terms and conditions outlined above still apply - we therefore strongly recommend that travel insurance be obtained prior to departure as no refund will be given. This offer cannot be used in conjunction with any other offer and is subject to availability. Blackout dates apply.
