Staying a month in Playa del Coco this coming Feb-March. Would like to go deep sea fishing 2 or 3 times. Most of the websites I have researched on line for fishing charters in that area seem to be charging $500 and higher for half day fishing. (this seems a little high compared to other places we have fish in other parts of the pacific and caribbean) Should I be booking on line and with who?? or am I better off dealing in person when I get there??
