On the Town
Shopping and other Diversions
Aruba has plenty of shopping opportunities for souvenirs and mementos. The low import duty rate (of 3.3%) and the absence of any sales tax keeps costs on a number of items very low. 
You might consider jewelry or perfumes here. Also, Dutch products, like cheese, chocolate and porcelain are worth considering. You may be amazed with the sheer volume of high-end Swiss watches, gold and precious stone jewelry, Cuban cigars, fragrances, crystal, liquor and English china. This is the place to buy quality products from around the globe. Be careful though - not everything is a deal, and you might end up paying much more than you would have at home. Some quick online research should equip you with the knowledge to make informed purchases.
Aside from the florin, stores also accept US dollars, credit cards and travelers checks. The sticker price is what you pay - remember no sales tax. Dickering over the prices is not culturally acceptable, like you might find in other countries.
Where to shop? You should consider Renaissance Mall and Marketplace, with more than 100 stores, 20 restaurants & cafes, and a movie theatre. Also Royal Plaza Mall and the Alhambra Moonlight Shopping Centre. For a current offering, reference the handy visitor guide you will receive when you land in Aruba. This will contain new stores and new products being carried.
Evening Entertainment
As mentioned above, its best to reference the tourist guide you receive upon arrival, to know about the upcoming events and stage productions. There is always lots going on - live music, theatre, and events.
