The beaches are really nice. Two of the top rated ones in Aruba are Palm and Eagle. I've stayed at the Marriott on Palm twice. On my upcoming cruise (2 weeks from Saturday!) plan to go to Eagle. Eagle is closer to port. There's a more remote beach - Baby Beach - that's a calm inlet. I recall facilities are minimal. At Eagle or Palm you'll have lots of facilities and places to eat. Aruba water is warm, calm and there's always a breeze. Up near Palm you can windsurf if so inclined.
