Headed to Costa Rica and staying at the Marriott resort in January. Looking for guide recommendations for a day of fishing for 4 people (2 younger boys).

I would recommend trying the outdoors board.

Bump and did add it to outdoors.

We stayed at that resort several years ago. I used a local company called Piko Travel to book all excursions and airport transport. Very reliable and great communicators. They can probably find you a fishing trip out of Los Suenos.

I'd use them again in a heartbeat. They are very highly rated on Trip Advisor and can find you anything in the area.

I had one client use this company: Los Suenos Fishing Charters and they said it was excellent!
