You can still pay with Florins where ever you go in Aruba.
Fact of the matter is that Arubans also love the american chains. I myself love Starbucks and would like to have a Starbucks in Aruba. People often say that Aruba is too developed and to Americanized. Well I believe that when you cruise through Aruba and go and explore the rough side of Aruba you discover the REAL Aruba. Approximately 38% of Aruba is not developed or not built on. Only the downtown and hotel area are developed.
