I will be traveling to Quepos in July. I am traveling on my own and am looking at the best option for travel from SJO to Quepos. I know the private transfers are pricy given that I would be reserving it for just one person (the cheapest I've been able to find is $130 one way). I've seen mixed reviews on the shuttle services but the 3 that have been recommended are Easy Ride CR, Grayline and Interbus. Does anyone have recommendations or experiences with any of these?
