My friend and I will arrive in Dar at the beginning of October. We going to stay in Tanzania for 12 days. It is on budget trip but also might be once in a lifetime so want to do as much as possible. I would love to see Kilimanjaro and safari but she is more interested in Zanzibar. I’m not sure what would be the best option to take. Can anyone suggest whether we need to plan everything in advance ( now) or it’s possible to book everything from there. Also flights...do we need to book them now or can we do it whilst we arrive at the Dar es Salaam airport. Thank you for any advice.
