Question: If I am leaving from Indiana do we need passports?  also what is time difference there? 

Answer: Aruba's currency is the guilder / florin denoted by the letters 'Awg.' but also widely known as 'Afl.' The official rate at which banks accept U.S. dollar banknotes is Awg. 1,77 and checks at Awg. 1,78. The rate of exchange granted by shops and hotels ranges from Awg. 1,75 to Awg. 1,80 per U.S. dollar. U.S. Dollars are widely accepted in Aruba, and banks may exchange other foreign currency.\n\nTraveler's checks are widely accepted and there is no charge for using them in hotels, restaurants and stores. Major credit cards are accepted at most establishments while personal checks are normally not accepted. \n\nThe Aruban florin is divided into 100 cents and there are coins of 5, 10, 25, 50 cents, 1 florin (100 cents) as well as the 5 florin coin. The square shaped 50 cent "yotin" coin is probably Aruba's best-known coin. \n\nBanknotes are issued in denominations of 10, 25, 50, 100 and 500 florins. Many souvenirs are made with the square 50 cent coin while the coin itself makes a unique gift for numismatic friends.\n\nCash may be obtained with MasterCard, Visa and American Express cards at credit card offices, banks, in some casinos and via Western Union. ATM cards and credit cards are accepted by ATMs of Aruba Bank, Banco di Caribe, RBTT Bank, and Caribbean Mercantile Bank. The card must have either a Cirrus or Visa Plus logo. ATM instructions are normally given in Dutch, English, Spanish and Papiamento. Cash is normally dispensed in local currency.\n\nTravelers with ATM cards bearing the CIRRUS, MAESTRO or Plus System network logos can withdraw cash in Aruban florins. Home bank accounts will be debited in dollars at a favorable exchange rate, and a 1% - 3% service charge will apply, depending on your credit card company. Before departing for Aruba, it's important to verify whether your PIN number will work in Aruba by calling 1-800-4-CIRRUS\n\nAruba is in the Atlantic Standard Time zone. You didn’t say what time zone you are in (Indiana is in two time zones).  If you’re in the Eastern time zone, Aruba is one hour ahead.\n\nPersons planning to visit Aruba as a tourist for a period not exceeding 90 days for the purpose of recreation, sports, health, family reasons, study, religious purposes or business must submit the following documentation:\n\n·A U.S. passport.\n·The necessary documents for returning to the country of origin (valid permanent resident document)\n·Proof of sufficient funds to stay in Aruba;\n·Return or onward ticket and other documents required for the next destination (visa etc.).\n\nNon-compliance with one of the above mentioned documentations might result in refusal of entry to Aruba. The immigration of Aruba based on the funds the tourist is traveling with shall determine the period of stay in Aruba.\n\nTo: Miss Demanda,\n\nHow many people are missing or killed here in the U.S. every year?  Should all foreigners stay away from the U.S.?  \n\nHere is a quote from an MSNBC news article on Natalee Holloway:\n\nViolent crime is virtually unheard of here. Last year there were two murders, I believe, and those were considered to be drug related and that was it. There were maybe six rapes. When you are talking about an island nation with so many visitors, that is considered an extremely low crime rate.
