Just to add: Just finished a two night Salt Flat tour yesterday (so in May). Got to see the mirror effect and yes, that was one of the most beautiful things I have seen in my life. So not entirely sure that going after April is such a bad idea. Our guide told us that there is basically never a guarantee that you will see it (eg. If there is wind).
Also, the tour is so much more than just the mirror effect. The salt flat perspective photos, mars like landscapes, canyons, hot springs, geysers, flamingo’s, red/blue/green lakes, etc. All of which are much easier to see in the dry season. For example, if you go during the wet season, most tours - from what I understand - will stay one of the two nights in Uyuni (the city) and not two in the middle of nowhere (which I found to be amazing!).
Hope this helps anyone!
