Good Question and I hope to put an arrival based trip report up tomorrow but in case I can help before that goes up. Smooth sailing is a somewhat relative term. Upon arrival on the island it was smooth as far as fewer people made things go faster. There was a "oh crap" moment where the health screener wanted to question our results but her supervisor quickly over ruled her. Only took a few minutes.

Note: You do have to show your negative results + your approval document at the screening and again at customs. Having it on your cell phone is fine but it would have been easier to have a print out.
