I recently did an "island hopper" from Manila > Palau > Yap > Saipan (via Guam) > Guam > Honolulu.

I know it's not the 'official' island hopper discussed in this thread but it was still great. I'm still working on my trip reports from Saipan, Guam, and Honolulu, but the links to my Palau and Yap posts are below - I figure they might benefit those reading this thread in their own planning!
