As cool as the island hopper is to experience, you can end up in non rev hades. At every stop, you will be asked to leave the plane as a non rev for a new seat assignment. The last leg from Chuuk to Guam is frequently jammed full and often weight restricted. Since there is not daily service from Chuuk to Guam, you can get stuck in Weno which is basically Newark after dark.

If you want to holiday in Palau, go the lesser risk route. Delta NRT is 4X/week and United is daily via GUM (2Xweek routes with MNL/1day YAP). Palau is amazing place although the Chinese tourist blow up has not been kind.
