I am a female traveling solo to Costa Rica in July, and I was going to take buses between destinations until I read several times that it is quicker/easier to use a shuttle van. However, when I looked into this, I read all of these bad reviews about popular van services, particularly Grayline and Interbus. Should I just take the public bus? I really liked the idea of hotel to hotel service, but I read that these vans don't show up or don't drop you off at your hotel. Can anyone recommend an alternative company that is not expensive? Are there other options? Any advice on this would be greatly appreciated!
