Need a WIFI connection for your laptop go to the Setar desk in the arrivals area before you leave for your hotel and buy a prepaid access card - $35 for a week of access, other options available, It’s easier to do this at the airport rather than trying to find an office to buy the card later. Here is their web site for more info http://www.wifi-aruba.com/

All the major hotel chains have resorts here, Riu Palace Aruba. The Westin Aruba, Radisson Aruba, Holiday Inn, Marriott, Occidental and more and are located on the west side of the island either on Palm Beach or Eagle Beach.
Lower your requirements for luxury and you can find numerous hotels and guest houses at reasonable prices, although you may have to walk a little bit to get to the beach. All beaches in Aruba are public and free.

Getting Around:
Rental cars and jeeps are available in addition there is an efficient and inexpensive bus system that connects the hotel zone with downtown Oranjestad and other districts on the island.

Oranjestad the capital, is named after the Dutch royal house of Oranje, and has been the island's capital since 1797.
The best way to explore the town is on foot. Public buses run from the hotel zone into downtown Oranjestad.
Shopping: Lots of designer boutiques and shops in the Seaport Village Mall and surrounding streets where you can get Delft China, Colombian Emeralds, Dutch cheese and whatever else you may need, and if you have some money left over you can go try your luck in the casino attached to the Mall. The Renaissance Aruba Hotel is located here as well.

Cross the road and you 'll find yourself at the yacht basin. Plenty of little souvenir shops here and if you're looking for fresh produce or fish you'll find that here as well. Adjacent is a marina and the Seaport Village Marketplace with numerous little cafes, boutiques and a movie theatre showing the latest Hollywood blockbusters on 6 different screens.

You'll find several small shopping complexes scattered around the hotel zone, newest one is right across the road from the Holiday Inn Sunspree Resort.

Aruba is also a port of call for many cruise ships and when they arrive in Oranjestad it can get a little hectic, so you may want to try and time you visit into town when the ships aren't in port.

Beaches:
Aruba has stunning beaches for swimming, sunning and windsurfing and I've have listed some of them below.

Arashi Beach - just south of the lighthouse near the northwestern tip of Aruba superb swimming/snorkeling in calm water. No facilities, some beach huts and you can get here by public bus although it's about a ten minute walk from the last bus stop.
Malmok - just south of Arashi Beach and great snorkeling, lots of fish to see.
Fisherman's Huts also known as Hadicurari - this is where the Windsurfing competitions take place you can take lessons and rent equipment here.
Palm Beach calm water and where most of the major high rise hotels are located and therefore lots of people on the beach.
Eagle Beach lots of shaded picnic areas and plenty of parking right off the main road. Several hotels just across the street from the beach. Not as busy as Palm Beach
Baby Beach calm swimming cove, is located at the southeastern end of the island, near the oil refinery.

Things to Do:
Go windsurfing or kite surfing at Fisherman's Hut Beach or take lessons here so you can tell all your friends back home you did.

Rent a jeep and drive around the island, it's not that big and it's an easy drive. Along the way you can visit the California Lighthouse at the north end of the island, and maybe even stop for a quick round of golf at the Tierra Del Sol Golf Course then towards the Alto Vista Chapel (the first established church in the Caribbean). Close by is the Ostrich Farm where you can learn everything you wanted to know about the 80 ostriches living here, and then move onto the The Donkey Sanctuary for more encounters with the animal kingdom.
Continue your drive and you will eventually get to the Natural Bridge a 100-foot-long natural arch 25 feet above the sea, but this famous Aruba landmark is no more, it collapsed in September 2005 and is now a pile of rocks.

The Bushiribana Gold Mill Ruins where more han 3 million pounds of gold was once produced is an interesting stop. Further down the east coast you will come across Sand Dunes and then round the bend at the south end of the island and you can pay a visit to Baby Beach a nice quiet relaxing beach. At this point you can head on back up to Oranjestad and stop off in San Nicolas at the famous Charlie's Barthat's been around since 1941. From here it's about 20 minutes back to Oranjestad and then another 10 minutes to the hotel zone. A good way to spend a day exploring.
And if the drive didn't satisfy your curiosity For something truly different visit the Butterfly Farm (across from the Aruba Phoenix Hotel) in the hotel zone.

If you don't feel like driving there are plenty of tours offered to keep you occupied, some of which I have listed below.
