Do I have to return the scoot to the location where I picked it up?

Nope! You can pick a scoot up at one location and drop it off at any other location, as long as the app says there’s room to park and you choose that location as your drop-off in the app. You can also use the app to change your drop-off while you’re out riding. If you want to return to the garage where you started, you don't have to choose a new drop-off location.
