Just do it!

South Africa was my second ISV trip. I loved Costa Rica so much I wanted to do another trip and chose SA. I can honestly say all of the money I spent was completely worth it. I 100% recommend anyone even considering it to just do it and go because it will be the best time of your life. You have opportunities to do and see so many new things that you can't do anywhere else in the world. The ISV staff are always great and super helpful and the other volunteers are so much fun. I left both of my trips with over 20 new friends from all over the world.
