Every guest booked on this offer will be entitled to a free upgrade to the next level room type, which will be allocated before you arrive. Room upgrades are subject to availability, and if your next-level room is not available when you arrive, we will be unable to give you the free upgrade.  

The Castle Hotel is currently undergoing a total transformation, and the main house bedrooms are not available during the period of this sale.  Therefore, the only room upgrades available will be to a Park Wing Superior bedroom. Supplements will apply to upgrade your room further. All bookings are fully prepaid and cannot be cancelled or transferred. The winter sale offer cannot be used in conjunction with any other offer, promotion, or discount.
