We plan to make a Salar de Uyuni tour starting and ending from Uyuni. We plan to take the early morning flight from La Paz to Uyuni (reaches in Uyuni at 07:15) and start the Salar de Uyuni tour on the same day.
1-) Is that reasonable?
2-) Any company you would recommend?
3-) We may have time to do either 4D3N or 3D2N tours. Which is the best and what may be the difference?
