I'm surprised that the percentage is only 16% (curious how they derived that metric, too...). I'm curious what the tourism market looks like (eg. where people come from and where they go). My assumption would be that the majority of tourists from the USA, Europe would just use their credit cards without knowing better or feeling comfortable with cash exchange.
It looks like tourists from USA, Canada, and Europe account for 26% of tourists here, but that doesn't directly translate to dollars spent:
