Before you have placed your order
You can change the number of players on the checkout page for each tee time in your cart.
After you have placed your order
To add an additional player to your round, you must book another slot for the same tee time (if there is still one available). This will place a new order, with a new order reference. Prices for tee times can vary and are not guaranteed to be the same as the price at which the original tee time booking was made.
If you want to remove a player you must cancel the tee time and then book it again with the right number of players.
