While searching for a non-Internet digital Spanish/english/spanish dictionary, I found this site:
http://www.spanishdict.com/
The site features the dictionaries of course, over 300,000 words. It also features a verb conjugator, a three-site translator, Spanish lessons, videos and games... there's a lot here.
I was thinking about where my Spanish needs to improve. Conclusion? Grammar, and this site seems to offer some really good educational materials. Haven't had too much time to fully explore it yet. Check it out, and let me know what you think.

Hope this helps you get more out of travel to Costa Rica!
