These Hop-On Hop-Off tours are not only informative and entertaining, they're also a great way to get around Honalulu, Waikiki and surrounds. The driver (we had Mike R) tells you about the sights, fills in the history, and not only knows his stuff but bends over backwards to give useful information generally. My tour (we've done one so far, but plan to do more) took two hours, but felt like half an hour. We plan to take it again, getting off at various stops to explore and then rejoining the bus (one comes every hour). A great way to get to know Honalulu!
