I think that's the right approach-- taking the mindset of "capture points where we can". The alternative, gunning hard to maximize CC points from the wedding, could be a major turnoff to your daughter, prospective son in law, wife, and other close family members.

Note well what I wrote a few posts above about how most people don't care about milking CCs for rewards points. It's a frequent topic of conversation here on FlyerTalk. "I'm trying to get my spouse/sibling/friend/colleague to see how many thousands of dollars they're leaving on the table by not playing the CC points game but they just keep telling me to shut up about it! What's wrong with them?" What's wrong is thinking that any given person shares our interest and priority in this game. Most don't.

Think how that would play out with close family members if they aren't 100% on board with your plan. Imagine your daughter going over the wedding photos when she gets back from honeymoon.... "Here's us sharing a slice of wedding cake... And there's Daddy in the background arguing with the caterers about which credit card they were supposed to bill so he could earn an extra 5,000 AA points."

Don't be that kind of father of the bride. Offer the idea of milking CCs but be ready to back-burner it if they're not interested.

And best wishes to the bride- and groom-to-be.
