The hourly rate vary throughout the day from $85 (between 12AM-2AM) to $355 (between 6PM-9PM).
Since most time slots are booked in advance for Seasonal Court holders and weekly programs, the availability can be very limited.
However, we always get cancellations, so you can use the "Appointment Finder" here to find a time slot (from today, up to for 7 days in the future)
Just select "60min Main Court @ Vanderbilt" as the Appointment type, then tap tomorrow's date, then Search.
