we took the fast ferry from stone town to dar es salaam to catch our flight out, and it was quite nice! the first step was spending basically an entire afternoon sweatily trying to procure ferry tickets by pushing to the front of a large group of people much more skilled than me at the art of not getting in a line. definitely do this the day before, as multiple folks missed the last ferry that afternoon because this process is exceedingly inefficient.
in dar es salaam, we used some hotel points for a free night at the holiday inn, and i went on a run on the newly constructed seaside barack obama boulevard before our flight home. a great time in zanzibar!
