Hello to both altheamann and Lyalll90, I work for Mahlatini, a UK based tour operator specialising in travel to Africa and the Indian Ocean Islands. In response to Lyalll90's initial post I think it is always worth shopping around a little to get a sense of the general market. Don't feel put off by getting in touch with tour operators directly, at the end of the day it is your decision and any reasonable organisation should be willing to talk to you openly and personably about the kind of experience you are looking for. With Mahlatini you are more than welcome to get in touch and have a chat with one of our specialists. If you like you can check out our site here
