Hi,
Kenya is a really fabulous place to be. However, if you are white, it will be rather hard to avoid the tourist traps unless you can get a Kenyan to do your bargaing for you...we still think white skin equals riches....student or no student.
Tight clothing or skimpy outfits fit better at the coast than in Nairobi, the capital city. Mombasa especially is a tourist hub and the hot weather allows for such....the rest of the country would frown on you...unless you are at a club in which case, the frowns arem more often than not leers.
It's rather safe but you need to take care...avoid deserted streets at all times and do not look lost. Ask for directions from a reputable looking shop along the street. People are very friendly anm more than willing to help...but like everywhere else, there are those that see potential easy money.
I'd suggest you visit Nairobi en route to Mombasa to relax on the cleanest beaches around and best weather....especially around November.
Nairobi has a few tourist worthy sights but the highlands and coast offer the most. Nairobi is busy but has superb nightlife.
You could send me an e-mail for more info. And I'm female in my early twenties too!! so no ulterior motives....
