This is a great use of points, flashy or not. Avoiding insane World Cup pricing and still locking in the exact dates you wanted is a huge win. That’s what points are actually for.
Mixing LifeMiles and Virgin with a transfer bonus on your first flight redemptions is impressive too. Those programs can be intimidating at first, so pulling it off cleanly is something to be proud of. And Hyatt during an event week is almost always where points shine the most.
cpp math aside, you saved thousands and kept your plans intact. That’s a success by any measure. Welcome to the rabbit hole.
