I am travelling to Tanzania next week, going on Safari in Selous and then onto Zanzibar. We are spending 2 nights in Stone Town and then 4 nights on the beach. Which location is best to stay at for the beach part of the holiday Nungwi or Jambiani? I keep getting mixed reviews. Ideally I don't want to have to walk miles to get into the sea. I'd also like to go diving when there so want somewhere with reputable dive centre. Any advice appreciated.
