Thanks everyone - yeah I did have a great time! It had its ups and downs, but that was part of the experience. I'm quite glad I got back safely too!
Legend, I visited loads of villages... I managed to do loads and meet lots of local people. I forgot that you went to Kenya - I'm sure your week there was good! The night safari was amazing; we got to see all the animals but we were all really quiet. It was funny because the next day on the day safari we were yelling and still saw pretty much all the same animals! It was quite scary though, because the spotlight needed to be shone on the bushes etc. and sometimes the animals ran off.
The light broke at one point and we had to wait around in this remote bit of the marsh whilst it was fixed... there seemed to be this big animal moving in one of the nearby bushes and we couldn't see what it was. I laughed when someone suggested T-Rex and we were actually in Jurassic Park (but it scared me at the time, obviously).
