Iolani Palace
The only royal palace on American soil, home of Hawaiis last monarchs and a genuinely moving place to bring older kids. Guided and audio tours take you through the throne room, the grand staircase and the upstairs room where Queen Liliuokalani was imprisoned after the overthrow. The palace had electric light and telephones before the White House did, which is the detail kids remember. Everyone wears booties over their shoes to protect the koa floors. Tours run on a schedule so book ahead, and note it is not a place for restless toddlers.
