Everyone has to do what they feel is best for them, but the risk to me is too great not to take a test before, even if it is fairly expensive, because of the real possibility of being asymptomatic. Possibly having to quarantine for two weeks on island is a bigger risk than I personally would take.
If I've been fairly isolated for a couple of weeks before I travel, it's pretty unlikely that I'm infected before I fly. Let's be real about this.
