Question about the Cruise in Hawaii

So I am leaving Tuesday for my Honeymoon.

I was wondering if anyone took the cruise around Hawaii these are my ports of call (Honolulu; Hilo; Maui (Kahului); Kona; Kauai).

I was wondering if you could recommend any good beaches on these islands.... Or some awesome things to see. Thank you so much I really appreciate it......

Never took the cruise, but on Maui - go to Kaanapali - Black Rock Beach right in front of the Sheraton. It's a great beach with really good snorkeling.

On Kauai - Northside I like Tunnels Beach - it's beautiful there. Southside, head to Poipu.
