Hi! I'm looking in doing a trans- africa overland tour from Uk to Nairobi towards the end of the year. I really want to secure a spot ASAP but am having problems choosing an overland company. Right now i'm debating between African Trails, Oasis and Keystone Journeys. I'm a female in my late 20's and traveling solo. I read some reviews of some companies being party buses. Although I would like to have some fun, i'm not looking for a 24hr party bus or feel like i'm in college again. Has anyone traveled with any of these companies and if so any you would/ would not recommend and why. Any input would be great. Thanks!
