For Los Suenos we use MROC. It takes a couple hours to drive from the airport to the marina but it's an easy trip on well maintained, 2-lane roads. The scenery makes the time go by fast. There's a small heliport approx. 100yds from the fishing boats at Los Suenos so if your pax are in a hurry a helo charter could be an option. For the crew, if you're there for more than 2 nights, I highly recommend staying at the Los Suenos Marriott. For <2 nights, the Marriott near MROC is a better choice.
