Hola,

 I am wondering if anyone could tell me something about their immersion experience during a short-term volunteer vacation.  I would like to travel to a Spanish speaking country but only have 1 week to travel.  I live in the USA so it needs to be a fairly short flight to make the most of my time.  I am thinking about Costa Rica but Cube would be even closer.  Any thoughts from anyone.  I have an intermediate level in Spanish currently and wondering how much my Spanish could potentially improve with just 1 week of complete immersion.  Any thoughts or advice would be greatly appreciated!
