The script manages holiday packages and it's actually a pretty good fit for travel agencies (regardless of other opinions). It provides a real time holiday package bookings, allows you to create custom holiday packages with different features and create your own customised filter by package type. Altogether with the user access level, the script provides the perfect base to create, manage and customise a travel agency website.
The only missing part is probably the tours – you can add only location – but not multiple tour destinations.
Anyway I think the script is great and I would recommend Stivasoft services to anyone.
