Phat,
Suggest you use the search feature here. That map link (and the oanda link for that matter) is on Costa K*D's links post which is on a sticky at the very top of the general info section. However, your mention of flyfishing made me think of a topic I don't recall having seen posted here I don't know if this would interest you, but I would like to know if any members have had any experiences with freshwater fishing in CR.
Here is a link you might find interesting on flyfishing in CR (which claims it has the best flyfishing in the world!?)
http://www.costaricaoutdoors.com/fishing-tropica-fresh2.htm. Lake Arenal is supposed to have some really great fishing. Two local fish, the guapote (rainbow bass) and the machaca, are supposed to be particularly challenging game fish. Here's another link for a day trip leaving from either SJ or the dam at the Volcano end of the lake (ie can easily be included with your stay near Tabacon/Fortuna/Arenal)
http://www.flyfishcostarica.com/trips/trip2.html. Don't know much about hotels on the Tilaran side of the lake, but the Tilawa is supposed to be nice with dbls running between $50-$120 depending upon view and time of year and offers a variety of fishing, windsurfig and biking tours.There is also supposed to be good mountain trout fishing in the Cerro del Muerte area going toward San Isidro de General. They have even have stocked ponds which I'm ashamed to say is more my speed.
BTW, taking intercity buses will save you money, but it won't save you drive time and sharing the rental car costs with a buddy(s) will drop the per person costs down considerably versus flying. If you want to squeeze in a little lake fishing on your trip, option 3 begins to sound more and more attractive.
