Plan a trip with friends
Put the stops on a map, add the places you want to go, and invite the people coming. Everyone edits the same plan, instead of a group chat.
Free. Start without an account; sign in to invite friends.

Add the stops in order and the dates. They go on the map, numbered and joined by a line.
By name, @name, email or a link. Everyone edits the same trip, and you see who added what.
Say which places you made it to. They land on your own map as been, with the day.
Each stop has its days and places, with ideas for things to eat, see and do. Open any place in Google Maps, or add the whole trip to your calendar. Changes show for everyone within seconds, and a daily email of what the others changed is there if you want it.
And it’s the same map as everywhere you’ve been, so the next trip sits next to the last one.
Yes.
Yes, to edit the trip: one tap with Google, or an email link. No app to install.
Only the trip: its stops, dates, places and notes. Not the rest of your map.
Only if you turn them on: one a day at most, on days someone else changed the trip.
Yes. Invite people later, or never.
