If you're an FPG member you can benefit from special pricing. All you need to do is insert your federated membership number in the proper field and tap Validate.
Please note that you should carry a valid number with you when checking in at the course.
At this moment, if you wish to book a tee-time for you and other golfers using the FPG membership number, your playing partners should also be FPG members. Otherwise, you'll need to make a separate booking.
If for any reason you get an error when trying to validate your number and the number is correct, please verify its status with the FPG or consult fpg.pt for more information.
