Luckily, we have 12 people on our flight with us so I plan on tasking each of them to take a carry-on. I also went and bought 3 large rubbermaid bins that have the lock on lids (that are in the checked baggage size requirements) and I plan on filling those up. That way if I need to leave them behind after the wedding, it won't matter. I got them on sale at Target for $6.99 each.
