How to add a document to my trip?
You can save documents in two places: the general trip or any activity.
Saving a document for your trip in general
In your Trip dashboard, there's a button "Documents" tap on it and after that, tap on the "Add a Document" button. Now you can choose between any type of document and include it in your trip. Of course, all documents are shared with your guests as well.
Saving a document to a specific activity
There's also the possibility of adding documents specific to an activity, like a flight ticket, concert ticket, or a hotel reservation if you want. To do that, go to the activity and tap the button "Add a Document" at the bottom of the screen.
