Cruising to Hawaii ... Looking for recommends near cruise ports

[+Team Bear-Cat]

We're leaving very soon on a cruise to Hawaii– yes, our own country – which will stop for one full day at each of the following US ports-of-call:  (Princess Cruises)

• Hilo
• Honolulu
• Kuaui
• Maui

 

We'd love to hear your recommendations about caches that would be available within or very close to the cruise-ports on each of these islands, especially those which would be accessible to geocachers of limited mobility.  (Not wheelchair-bound, but can't walk far.)

 

But we'd also like to hear about "oldest caches" or "memorable caches" which might be of particular interest to more able-bodied geocachers who might, say, stroll a mile or more outside the cruise-pier area, or rent a car for the day.  (We're capable of hiking and love to do it but must be mindful of the time.)

 

What do you suggest?  Which caches should we "absolutely not miss" on our upcoming adventure?
