The docks have a warehouse that is empty and the room description invites suggestions for how to utilize it. I propose letting folks run shops inside it such as many RL locales have done with old abandoned transit buildings. I for one would like to put a canoe rental shop inside, as this would give a little bit of space for the shop as well as a protected construction area for the canoes. All the usable exits to the shops would be from within the warehouse itself to keep from cluttering the dock area.
There would need to be the understanding that derelict shops would get removed (unlinked but not deleted so it could be restored if necessary) after a certain point of time. (Perhaps a review of the shop owner activity every month, and removed after 6 consecutive no-shows or something?)
