They do have their own “dollar” (known as Bahamian dollar), its interchangeable with US Dollar as its a 1:1 peg meaning value remains the same (B$100 also equates to $100) but they have a bill for $1/2 (50c), so there are 8 denominations & it’s a strong currency with a caveat (it’s closed, it can’t be exchanged outside the country). I know it’s a rich country not too distant from Florida, have you been there before? If so, what is it like?
Go-to Aruba during the summer. It’s like half price of their winter rates, and they have the same weather year round.
