If you can afford it do both! You have to be up for the "cruise" part, but it can be so easy and as Leejnd4 mentioned there's an added social benefit if you like meeting new people. It generally attracts people celebrating anniversaries and those who've just fallen in love with FP and become "regulars". Depending on how far you are traveling to get there and whether you will get the chance to return to FP, the PG boat really allows you to see so much in such an easy way. Each island feels like a new paradise on and off the boat. We ended our trip with a stay at an OWB which seems to be a bucket list for many and it was a perfect way to relax after a week of touring the islands. While the ship is relaxing in a different way, every day we were doing something, at the bungalows you could just look out at the beautiful sites and take it all in, my husband commented that snorkeling was our "excursion" of the day.
