Hiring 4x4 in Tanzania and ferries to Zanzibar
We're planning a holiday for March next year, and we're going to do a safari tour in Tanzania, but we want to spend a couple of days in Zanzibar afterwards. I know you can technically fly, but I'm more keen on seeing the country. Maybe renting a 4x4 and driving across Tanzania. Has anyone done this before? Is it safe?
What I really wanted to ask was are there only ferries to Zanzibar from Dar es Salaam? I'm looking at the map, and coming from around Arusha, it's quite a drive. Does anyone know if there's a ferry from Tanga to Pemba or Zanzibar? Or should we just fly to Dar es Salaam and go from there? I've heard that Pemba has a more chilled vibe than Zanzibar - any other experiences? We're not really big party people, we kind of just want to lie on the beach, can we get that in Zanzibar too?
I'd really appreciate some advice, thanks!
