Surely there's a way to do it better than just over text? It's a 4-dimensional (time and space) experience isn't it: "After lunch on day 2 of the vacation, what attraction do you want to visit?", or, "When do we have time to squeeze a visit in that café that all the Instagrammers post about? [Yeah, like it or not this is the reality]".
A Miro[1]-like collaborative map would be interesting, every participant of the trip can vote what they want to see, the app can calculate the best itenerary (route and time), maybe even split up the group if some members are really not interested in some things (e.g. a visit to the local football team's museum, or the 5-star steak restaurant where there are vegan members).
It's more than a 4-dimensional space - it's a probability distribution over 4-dimensional space, one that you want to explore ahead of time, and you never really know for sure where you're on it until your trip is over. I'm yet to see a planning tool that handles this.
What I mean by the "probability distribution" part is, your trip plan isn't really a specific plan - it's a set of possible plans. You may have concerns like, "what if we arrive late on the first day?", or "what if the main attraction for the 2nd day is closed", or "we're not sure at this point where we'll eat", or "oh crap, it's raining today, what do we do?", etc. You have to navigate these questions in your head. I'd love to have a tool that makes this easier.
