What each number says
ADR is the average rate of rooms you sold. RevPAR is that rate spread across every room you could have sold, empty ones included. A high ADR with a half-empty shoulder week can be a worse result than a lower ADR that filled the house.
Festival peaks in India punish the opposite mistake: discounting to chase occupancy when the city was going to fill anyway.
What should drive the meeting
Use ADR to see rate quality and RevPAR to see commercial result. Do not let either number, alone, set the next restriction. The RevPAR calculator on this site is a worksheet, not a forecast.
