Suggested Itinerary Builder plugin specifications discussion

I think it would be great if there was an Itinerary Builder plugin, but the reason I haven’t put this thread in Feature Request section is that I don’t really know what I/we are asking for. I would really like input from other users as to what they think should be in an itinerary builder.

I know there is already the GD List Manager, but I suggest that Itinerary Builder would be much more than GD List Manager.

While Whoop is an obvious theme for this to be integrated with. I would like to use it with Supreme.

Itinerary Builder Vision
GeoDirectory end users could either create or import pre made itinerary from other users and modify to suit their needs. Ideally the Itinerary builder would use as much existing information as possible. Information would be imported from existing information in the GeoDirectory listings and additional sources like Google Maps for directions and public transport information.

When I create an itinerary for a trip I often like to have a very detailed plan for each day which includes:
Accommodation

For self guided tour day:
Points of interest (attractions/place)
Including keep points at the point of interest to see and ideally with the option to add photographs or link to map with finer details.
Suggested time to spend at the point of interest or exact time if needing to reach transport at a particular time.

Extra information like entry cost or details on any pre purchased tickets.

Directions to point of interest including public transport with Train Station (platform number) /Bus Stop and service name or number. Stop to get off at. Ideally this information might be imported from Google maps, GeoDirectory place listing or entered by the user.
