STI stands for Simple Tour Itinerary. It provides a concise and summarized version of the tour, typically covering the day-by-day itinerary, hotel and meal options, package inclusions and exclusions, flight details, and terms & conditions. It’s ideal for quick sharing, previews, or when you just need an overview of a tour.
In contrast, a tour package is a comprehensive version, it includes not only the full itinerary, but also detailed cost structures and pricing.
