Spanish immersion program for fun

I attended Intercultura in Heredia, Costa Rica to help improve my Spanish. It wasn't a requirement and something I did on my own volition--like the majority of students I met there. I thoroughly enjoyed the program. The classes and professors were great, the extra cultural class options were fantastic. I didn't love Heredia though. We were advised not to be out after dark on the street and to take a cab home if we were out late. I prefer walking around so this wasn't great to hear. I was home every night by sunset at 6pm to avoid roaming the streets after dark. My host family was pretty nice. They hosted a ton of kids. One of the family members wasn't as nice, but she was around the least, so I didn't have to interact with her a ton. The house was nice, too and the cooking was fabulous.
