How does he golf membership work at Belleville, assuming my son and I are playing. The fee sheet says:

Green Fees
9 Holes - $20
18 Holes - $30

Cart Rental
9 Holes - $10.00
18 Holes - $20.00

so I assume if we get a cart the 18 holes is $100? Is the correct, pricing out whether Cinco Ranch via Arcis, is a better option.

From looking at the website, it says unlimited golf is included for your membership fee. So you shouldn't have to pay any green fees and likely still have to pay a cart fee for you and your son.

But I've never played there and don't know anything about the membership. So may be worth confirming with them. But that's definitely the way I take what they have on the website.
