Since the treatments at Banyan Tree Spa Macau are in high demand, advance reservations are advised. Forbes Travel Guide Four-Star Banyan Tree Spa is popular not only with hotel guests but with the local community, so it’s recommended to secure a preferred date and the type of treatment at least 24 to 48 hours in advance. It’s easy to book your desired treatment by phoning the spa from inside the hotel or using its spa reservation website. When you make your reservation, a credit card number will be required to hold your appointment time. Should you need to cancel or change your appointment, please be sure to call at least 24 hours ahead of time. If cancellations are made with less than four hours’ notice, the Macau spa will charge 50 percent of the fee for the missed service to the credit card on file.
