Abstract: User interface showing timed and sequence events interleaved in a travel itinerary is disclosed herein. According to a preferred method of the present invention, the planning begins with a particular day at a destination. Next, ad hoc activities are created as a list in no particular order. Generic activities are also included in the list. A user will then drag the generic and ad hoc activities (bookmarks) that will themselves become either timed bookmarks or sequenced bookmarks. The timed bookmarks have a particular start and end time while the sequenced bookmarks will not have a definite start and end time. Once the planning is completed, the trip information should be shared with others involved in the current trip, as well as others that will plan subsequent related trips.
