I haven't been there for a few years. However, when I have booked an appt. for massage, (at either the GF Spa, or at the Mandara Spa over at the Dolphin Hotel), I found that it was easier to reserve on short notice -- if you looked for either mid-morning or mid-afternoon times. This is because people are either usually in the parks or at meeting/conventions during those times; whereas, an early morning appt., lunchtime break appt., or late day/evening appts., might be more "peak" times for their clients.
