Fairmont Ambassador Seoul, an Accor luxury hotel, has shared results from implementing the IDeaS G3 Revenue Management System. The property went live in October 2025 after deciding that manual pricing, forecasting and overbooking decisions were too slow for a market where demand shifts quickly around events and holidays.

What was breaking

Before IDeaS, the revenue team adjusted rates and inventory by hand, using short-term booking pace and daily pickup. Visibility across a full 12-month horizon was limited, pricing structures were relatively fixed, and overbooking calls rested on experience rather than scenario modelling. Manual forecasting also took time that could have gone to strategy. Joy Jung, Revenue Manager, said visibility beyond the short-term booking window made it hard to identify demand patterns across the year.

What changed with G3 RMS

With G3 RMS, the hotel receives recommendations based on its own data and updates rates several times a day across the booking horizon. Tools such as Investigator give deeper views of demand drivers and booking behaviour. Jung described the onboarding as structured, collaborative and well supported, which helped the team bring the system into daily practice.

Reported results

• Suite revenue contribution rose from 17.0% to 18.7% year over year
• About KRW 512 million (roughly USD 372,000) in additional suite revenue
• About five fewer hours a week spent on manual pricing strategy work

IDeaS says the hotel has shifted from a reactive posture to a more forward-looking approach, with closer alignment across Revenue, Sales and Marketing around a shared view of demand.
