Seven cities, no fixed order, and a spreadsheet that could not cope.
The first version of Vayou was a spreadsheet. Seven cities across Latin America, two to five nights in each, two or three flights a day between them, and no particular reason to visit them in any given order.
That is 5,040 ways round before you have picked a single date. We tried to do it by hand, got about a fifth of the way through, and booked something worse than what we started with.
Vayou is that spreadsheet, rebuilt properly. It reads every order the trip could go in, weighs them against how you actually like to travel, and hands back one itinerary. The part we used to spend a weekend on now takes under a minute.
