While you can book in Uyuni the risk is that you won't be able to get on a tour the same day and have to wait around until the next day and to be honest there really isn't much to do there. You can book in La Paz at one of the many travel agents or online if you know exactly what date you want to go.

hi Tania, the guys from Chimu are right, book in La Paz with an agent in advance if you can or a site like this one - http://www.rutaverdebolivia.com/uyuni-tours.php
Uyuni is very dull and is only there to act a doorway into the Salar. You may, however, just need a day to recover from the bus ride from La Paz that brings you there, 12-15 hours of fun (not). A 3 day / 2 Night Jeep driving tour of the Salt Flats is the best, you get to see a lot. Bring a phrase book, almost none of the Jeep drivers speak English
having said all that, the Salar is one of the most stunning places on Earth

Loads of offices, there will probably be a tour free on the day you want, unless you're in a big group. Also you can check out the quality of the meals/vehicles/drivers better in person, you can always get a taxi to the train graveyard to pass the time, there's also a trip to the working silver mine in Potosi to consider, I'd just turn up, you won't be seriously inconvenienced IMO. Curiously some tour companies weren't accepting people from certain countries and the hostels weren't too friendly, even quite hostile... Uyuni wasn't the best first impression of Bolivia for me (glad to say it wasn't representative of the whole country!)
Any time you can spend on the salt flats is good! Magical place, sleeping an extra night to catch the sunset/rise on the flats themselves (not just the geysers) is wonderful, take a camera (and shades!) over 8 years ago
