Glad to help. First time visitors should book a desert tour, it's a full day of sun & fun.
-----------------
Pick up the free "stuff" at the airport arrivals from Divi and from Little Switzerland - there is no obligation.
-----------------
This country offers US pre-clearance - TSA, Immigrations & Customs is on the island so you do not have to do it upon arrival in New York. Weekend departures are busy due to timeshare visitors leaving.

You will fill out a form prior to arrival and Aruba Immigration will give you a portion of that form to keep and surrender upon departure - keep it safe with your passport.

-------------------
It is advised that passengers arrive at the airport three hours prior to departure to ensure enough time to check-in with your airline and clear customs.
You will clear U.S. Customs in Aruba, not the United States. As an added convenience for passengers to the United States and/or Puerto Rico, Aruba has an agreement with the United States government to provide the services of the Department of Homeland Security/U.S. Customs and Border Protection (USCBP). When passengers clear these procedures in Aruba, passengers are not required to clear them again at their final destination in the U.S.
1. Check-in with your airline in the U.S. Airline Terminal. Have your passport ready to show the Airline Agent. It is not necessary to show the Agent your airline ticket/E-Ticket – the Ticket Agent only needs to see your passport to check you in. After the ticket agent confirms your reservation and seat assignment, you receive your Boarding Pass and “U.S. Customs Form” (one form per family). The Agent will take your luggage and put them on a conveyer belt. Note: This is NOT the last time you will see your luggage (see #7).
2. Proceed outside to the Departure Building (left when facing the Departure Terminal).
3. Outside the Departure Terminal, an Aruban Inspector will check your boarding pass and passport.
4. Inside the Departure Building, proceed to the booth where you clear Aruban Immigration. The Agent will check your passport and boarding pass. Here you will turn in the stub of your Tourist Card that you received upon arrival.
5. Proceed to Aruba’s X-ray security.
6. Pass through an area of Duty-Free shops and food eateries. As there are tables and chairs in this area, you may want to fill out the “U.S. Customs Form” here.
7. Enter the “Baggage Claim Area”. Retrieve the luggage that you checked at the Airline Ticket Counter. There are free luggage carts in this area. Note: The “U.S. Customs Form” must be filled out BEFORE you leave the Baggage Claim area.
8. With luggage, proceed to the next room to the U.S. Immigration and Customs booth. The U.S. Agent will check your passport and boarding pass and take the “U.S. Customs Form”.
9. In the next room, place your luggage on the conveyer belt. You may/or may not have your luggage inspected. At this point, you will not see your luggage again until you arrive in the U.S.
10. Next area is U.S. X-ray security.
11. Take the escalator/elevator upstairs to the gate departure area
