Let the relaxation begin, you’ll want to make an appointment as far ahead as possible for The Spa at Mandarin Oriental, Boston. Not only will this give you something to look forward to, but the Five-Star Spa at Mandarin Oriental, Boston is a favorite escape for both locals and tourists, which means it can book up fast. This is especially true on holiday weekends and during major Boston events, like the Boston Marathon or graduation weekends (end of April through the summer months). If you want some time at the spa (and you will), it’s best to make an appointment at least two weeks in advance to ensure you get the treatment and time slot you desire. There is certainly last-minute availability at the spa, but if there’s a specific treatment you want, it’s best to call a few weeks in advance to secure your appointment. You’ll receive a call from the spa concierge confirming your appointment the day before your treatment.
