Tracysue, it is very casual, atlhough the women still tend to dress elegantly at dinner. By elegant, I mean something you might wear to a summer garden party. Summer dresses, long wrap skirts with a nice top, nice pants, etc. Take a wrap or two, to help change things up, and in case the a/c is too cold. Dress it up with jewellery.
Men, short-sleeved shirts, nice khaki pants. Some wear golf shirts. Some wear long-sleeved shirts. No ties, no jackets unless the man wants to.
