I've never done that but my situation is different. Don't know if it would work for me. Now, I'm not married, have no kids, haven't traveled since just before the pandemic. I have maybe 1/2 dozen credit cards including Costco Visa (3% cash back on qualifying travel, restaurants too), Citi Double Cash Mastercard (which I use unless there's a better deal with another card, Discover (5% cash back on rotating quarterly basis), Chase (5% cash back on rotating quarterly basis). I've not paid attention to the travel points thing, seems complicated and I figured maybe I haven't been traveling enough for it to work for me. There may be better credit card(s) I can get, I think there's maybe a thread here on it that I lost sight of...
Is there an internet place that spells out the ins and outs of travel points?
