After having reviewed several websites and books, the consensus is to not drive oneself in CR. I would appreciate any input on guided tour groups. I have looked into Smithsonion,Elderhostel, and Nat'l Geographic. As an aside, let me say that tour groups are not my preferred style of travel. TIA, Joe

I like both. Before our first trip, I researched for about 85 hours online.

I was this close (|) to hiring a private driver. I wanted the input of a local driver on things one does not find on a map, or in a guide.

I chose to drive us and was anxious for about an hour. After that, it was fine.

For our next trip (which I am currently researching) I plan to combine both modes of travel, but do not wish to join a tour group and become one of many sheeple in a bus/van. I wouldn't do this at home, so I don't do it abroad.

I agree with triplesecdelay.
We just returned and drove ourselves. I would not have traded the freedom and flexibility for anything, especially a tour group. If you are fearfull, afraid of heights,a woman or women alone, etc,maybe hire a driver. We are late 40's live in NJ, if you can handle a NY commute CR is no problem.
Sorry for the spin but it sounds like you would just be happier with freedom.

My approach was either to fly place to place or take Interbus between places and book tours in specific areas.

We had a driver and would do it that way all over again.
