It was amazing and unforgettable trip.
Organization of the program deserve all credits, everything was ready and especially you wouldn't face insecurity or safety concerns.
Orientation day was full of information and even if you are alone or worried all needed is described and acknowledged.
I think that volunteering mostly about taking rather than giving, because you cannot count how much kids, country, people, experience, other volunteers contribute to your development, joy and happiness and you think that you never can do the same or more to community.
If you have doubts - try, if you are worried - try, if you just started to think about - try. It would be one of the best decisions of your life.
