I have seen posts from people complaining about the cost of internet access for visitors to Aruba. The daily cards can be especially expensive. You can get a week's internet access for $35 through Setar. Many of the resorts are hotspots. You can see the list at their website. If you're going to be there longer, you can get a month's access for $70. It works pretty well. I have used Skype to phone home.
