An existing reservation can’t be modified. To make changes to a reservation, you need to cancel it and make a new booking. Facts to consider before canceling a reservation:

• The reservation needs to be canceled at least 72 hours before the check-in date to get a refund of 75% of Gems.
• If you do not cancel the existing reservation at least 72 hours before the check-in date, then the average gem price of one night of your reservation will be deducted.
• A reservation cannot be canceled on the check-in date. 
• You need to be at the required VIP level to make another reservation.
• Room prices may increase/decrease since the previous booking.
