I'm intrigued about the "Trip Planner" being a top-level app. Only tried it in a very surface level way, but the recent trips I've planned (Ottawa for 6 people, Cancun for ~20) have ended up as an ugly mishmash of spreadsheets + google maps saved locations list + random chatgpt sessions.
It feels like there's an unmet need there for managing something more flexible than a minute by minute itinerary, maybe like a list of must-do and want-do activities and dining options, with the system able to figure out what is open when and has other constraints like the weather, costs, what activities pair well together, which group members some things are more or less suited to, what the contact details are for things like a private tour, etc etc.
