Trip of Trips is a city, things-to-do, transportation, and lodging organizer. If you use a spreadsheet when you travel, this is for you.
The more information you provide and features you enable (the next few slides) the more intelligence Trip of Trips will be able to provide about your trip (like weather and estimated city costs).
You can always download your trip cities, things-to-do, costs, etc as a spreadsheet if you'd like. See the tab in the planner.
