Hello I have booked on 5/26 Sunday at 9:32, 9:40 and 9:48 for our company competition. The total number of people is 10, it means 4+3+3=10 people.In case 3 people, does somebody 1 person join us in order to make 4 people? I appreciate your advise.

Yes good igeal to call them to clear anything up. Have fun.

Make sure you cancel the 3rd tee time adhering to their 24 hour policy. True commitment from players planning to show should be obtained by that time. As far a a single player joining you that is up to the course.

They can especially since it's a Sunday morning. I would call and ask them if you don't want others to join you.
