You should be looking at
www.aruba-bb.com and
www.aruba.com. I lived in Aruba for 7 months of the year a few years back and still go every year. I always check out the restaurant reviews, etc. Chalet Suisse is one of our favorite restaurants. Papiamento is very romantic (go at 7-ish after sundown and request a table for 2 by the pool). Understand that it is a leisurely dinner. DH and I go at least once each year. Agree with Barefoot. Also try Water's Edge at Costa Linda (it's right on the beach) on Eagle Beach. You will note from the websites I mentioned that Aruba is NOT dressy. You'll sometimes see ladies dressed up at the Hyatt (I gamble there once a week when the band is playing) but the norm is sun dresses/cropped pants with a nice top for ladies. Nice shorts and collared top for gents. You may want to dress up but it isn't necessary.
