For someone collecting countries the island nations prove to be the most difficult, especially if one doesn’t cruise.  There are 30 that I have yet to visit.  I met a couple who not only found themselves on one of the small exquisite boats but also a bargain as it was repositioning from one place to another….they hit the jackpot with four stops, all out-of-the-way places like Cook Islands, Papua New Guinea and Samoa.  FYI, I did get to Fiji!
