Any offers that Kuoni show in their brochures are guaranteed unless they state that an offer is subject to availability. When the offer of a room upgrade is mentioned in Kuoni Plus, it is not necessarily an upgrade to the next category featured in the brochure, but usually an upgrade to the next category of room available within the hotel.
Any room or meal plan upgrades offered will be given on arrival in the resort. On the itinerary shown on the invoice, the room or meal type shown will be the room or meal type that customers have paid for.
