Cancel/Reapply datapoint: Hyatt Visa cancelled 6/15/16 (applied/bonused in 2013, so well beyond 24 month) - reapplied 7/19/16 - instant approval (no 5/24 issues).
I waited until I got some closure alerts from credit monitoring services to be safe as relatively few datapoints on the "wait after cancel to reapply" timeframe here.
