Aruba is a place with the most dependable good weather I have experienced, any time of the year. If you like the beach this is for you as there is not much else to do. The island's beauty is the beach, and water. Underwater experiences are great. The cooling trade winds keep the temperature pleasurable. Those same winds make Aruba the wind surfing capital.
The local people are very helpful and friendly. Prices are fair for most all goods and services. The U.S. currency is always accepted and most things quoted in dollars.
