I'm going to agree, but with some qualifiers - I've taken them numerous times, and always had a positive experience - until my last trip in May - they sucked - period.
Also, if you take them, while you don't have to tip, a dollar or two to the guy w/ the clipboard and the driver is sufficient (not going to get into the whole tip or not in CR debate, but if you overtip, you might as well take a cab - you can - I did - negociate to $20 all in).
Here is another alternative and a good one - read the thread, and do not hesitate to use this option - the airport bus, especially if you are on a budget:
viewtopic.php?f=4&t=37524While at the airport, before you leave, walk across the street to the departure area, in the ticket lobby - walk in, make a
right and do 2 things:
Buy your exit visa ($26), you can't miss it - then its done and you don't need to mess w/ it when you are leaving
Just past where you bought your exit visa, is a bank - DO NOT CHANGE MONEY ANYWHERE ELSE, ESPECIALLY IN A "CAMBIO" - there are two of "Casa de Cambio's at SJO, and they both suck - Shitty exchange rate - just use the bank - in well over 30 trips I've accomplished both tasks in less than 10 min's and 2 less things to worry about, not to mention bank rates (vs hotel or casino)
Asume you have been reading; truly its worth the time to do so; can be overwhelming, but so much great info on this site - wish I had CRT when I started coming down in the mid 90's... in the Newbie section check out Oranges'- excellent hints - its a stickey - have a great trip
PS I know you did not ask about some of the things I've mentioned in this post but its info I would want ever new traveler to CR to have

and the bus, bank and visa are not "intuitive"
