  description: An upsell service that can be consumed to display upgrade offers to a hotel guest prior to arrival. Pre-arrival upsells are becoming increasingly important due to the adoption of mobile and kiosk check-in which reduces the opportunity for front-desk upselling. Upgrade offers are based on PRiME(R) AI/ML decision intelligence and OPERA real-time inventory. The service allows instant fulfillment of the upgrade offer.<br /><br /> Compatible with OPERA Cloud release 26.2.0.0.<br /><br /><p> This document and all content within is available under the Universal Permissive License v 1.0 (https://oss.oracle.com/licenses/upl).
