OBC 2 rooms, one credit card?

[ladygal4.4]

I hope this isn't too confusing. Here's the setup. My husband and I have 2 rooms since we have 6 in our family. So we each have our own booking number. Each booking number has its own allotment of OBC. So last night, I did the whole check-in/passports/and added our credit card to pay for additional expenses.

 

But then it hit me. Since I put both rooms on 1 credit card, will his charges use up his OBC first before going to the joint credit card? Or should I put him in another credit card.

Not sure what the difference is (why it even matters) But we have done the multiple cabins and have everyone charging to the same CC. Each person has their own Folio # but the "main" account holder will see everyone's charges on their screen. The OBC will be deducted from the running total of the accounts. So in the end the cruise charges- OBC total = final payment due and charged to the card.
