I work for the Danish Embassy and we process visas all the time. Your best bet is to contact the Embassys in this country for the countries you plan on travelling to. Be warned though, you may need to apply in person at the Embassy which more often than not is in London. Visas can also take up to 6 weeks to go through the system, so be sure to do it in plenty of time ..
BTW this only stands for what I know of the Danish procedures, Kenya and Tanzania will be totally different. Call their Embassy (or a Consulate local to you) and find out
