I have one question about this code at Marriott Grande Vista. It is a discount for Marriott Vacation International Owner (MOD code)

I am wondering if MVCI number must be presented at the time of check-in. On this property, three of four different type room rates doesn't require number (shown as below). But, the other rate (for largest 3 bd villa) requires MVCI number. I don't know if ID requirement mistakenly omitted in the other rates.

If anyone have any idea/experience, please let me know.
Thanks.
