We arrived in Uyuni after the Dakar Rally that had been in town had left and accommodation was finally available again. Fortunately we only spent one night there before setting off on our tour across the salt flats, as there really is nothing of any interest.
Uyuni has one main pedestrian street with a whole bunch of restaurants along it, and in the surrounding streets it has a bunch of tour operators, and that's about it. There are some statues and old train relics around the place, and a big clock, but that's it.
We spent the afternoon comparing tour operators. We had made a short-list of some from online reviews etc. Some of them we didn't find their offices and the main one we wanted to use was booked out for the next day, so we went with the cheapest of the remaining options. The tour was to depart at 10.30am the next morning.
