The Aruban Floran is the currency of choice for your Aruba Vacation. The US dollar should convert for at least $1.50 Aruba Floran each. However, be sure to convert only what you plan to use.
*The Floran will not buy you much outside Aruba, so convert back before you leave the island. Also, keep in mind that the ATMs will dispense Floran currency if you need cash.
