I would thoroughly recommend this programme to someone wanting a real experience, not just drinking on a beach (not to say you won't in Tanzania!).
Basically, you would be hard pressed to find a more beautiful country than Tanzania, obviously the national parks, and coast, but more amazingly the day to day scenery and culture.
On the programme, you are thrown head in, the work is hard but you get used to it pretty quickly. On this programme their is a lot more manual work which I enjoyed because it meant less faffing around teaching and all that, all of which I am a complete fail at.
The local people are amazing, if you take the time to get out into town not just in placement hours, I guarantee you will make amazing friends, and make sure you get the staff to take you out. Basically, you can very easily waste this trip by simply staying in the compound, and not experiencing what amazing opportunities are available every day,
Lastly, the staff were fantastic, the food was great and I have never had a more fulfilling period in my life.
