We will be going to 3 islands in 10 days and are wanting to pack light so we will have enough room for souvenirs. We have reservations for some really nice restaurants (Roy's, Alan Wongs, 3660 on the Rise) What do most people wear for dinner at these restaurants? Also, for places like Duke's, Hula Grill, Moose McGillicuddy's, Longhis?

Casual wear will take you just about anywhere. Women sometimes wear long Hawaiian dresses, a lovely look.

Men get by with hawaiian shirts/collared short sleeve shirts and slacks at dinner. Women wear hawiian print dresses or hawaiian shirts with skirts or slacks. Very casual.

Like anywhere else wendy if you want to dress up do so but dress casual is more the norm for the restaurants you mention.

Whatever you wear, do not wear anything formal for Moose's!
