The Other/Notes tab in Bookings provides extra flexibility because it allows you to display any kind of additional information in any part of the itinerary.
The Other/Notes tab lets you insert a trip overview, emergency contact information, packing recommendations or tipping guidelines. It can also be used as a shorthand way to insert a daily touring booking or airport transfer with minimal information.
If you do not assign a time for your Other/Notes booking, it will default to the very top of the itinerary for the date you have selected. So, if you wish to provide a trip overview as the first item in the itinerary, you should give the Other entry the start date of the trip and simply not select a time.
