There are several ways to book an appointment at Stillwater Spa. The most common is to call the reservations department directly. You may also book by emailing. If you’re staying at the Park Hyatt Toronto, you may book through the concierge or e-concierge. And of course, you can visit the spa front desk yourself and book in person. If you want to make an appointment during the Toronto spa’s busiest times — Friday, Saturday and Sunday afternoons — we suggest you book at least three weeks in advance. The Forbes Travel Guide Four-Star spa is open during the week from 9 a.m. to 10 p.m., on Saturdays from 8 a.m. to 10 p.m., and on Sundays from 10 a.m. to 6 p.m.
