yeah, i tried it out after I got back from CR. Not sure how much it costs, i used it on my friend's computer, but it seemed to be pretty good...picture to word association. I went there knowing very little Spanish and actually learned a lot just being there. I think it really depends on where your planning on going too. In CR, there were tons of people who spoke English.
On the other hand, def helps to know the language fluently, otherwise you'll end up in a situation like my friends' and I did the first night we were there. We went into Tamarindo and went to a couple bars and were heading home at the end of the night. We got pulled over by a cop, and he handed a breathalyzer to my buddy. He blew into it and the cop showed it to us. It said 5.0...haha not knowing much Spanish, I said "Tu Loco! He would be morte!", we then paid him 11,000 colones and we're on our way...lol
Koki Barrels - the quote in your signature is awesome, really rings true.
As for Rosetta Stone, I actually have it but haven't used it much. It seems like if I did it consistently it would really help, nothing compares to just submerging yourself in the language like when you're in another country though.
my son majored in german and spanish at west point,they sent him abroad to guatemala and austria,and when he came home the commercial came on tv and he said their claims are not true.he and his classmates tried it.lame
I'm really into learning languages for when I travel and the best thing I've found for getting a feeling of immersion before you go is the Pimsleur series. It's purely an audio course, available as CDs or a download. You do a half hour lesson every day, listening and repeating. The main thing is you have to do it every day, or else repeat the last lesson, because it's based on research about how often you need to have a word repeated to load it into your memory--the interval gets longer with each repeat, until finally it's in your long-term memory. Very efficient way of learning. You won't learn a lot of vocabulary from it, but what you do learn will be solid, almost as if it was your own language, and you'll have a good accent. It's best to supplement it with some sort of book for writing and vocabulary-building. I've used the Teach Yourself books in the past for various languages, they're generally good.
I've checked out Rosetta Stone a bit and haven't been that impressed with it.
Good luck and enjoy your trip!
