No, the custom course can me used as many times as you wish.
A custom course builder can only be used once.
The best way to get your moneys worth from a custom course
builder is to first make a custom course in your country club, they are free to
make. Then make a club tournament using the custom course. You will need a
custom course builder that does cost some coins, credits. Make the custom tournament for
a 4-week unlimited play tournament in your country club and you will be able to
play the custom course for the entire 4 weeks as many times as you want.
