How to handle multiple locations?

I'm at a fork in the road and looking for input. Should I limit each node to one location? My thoughts so far:

• My directory already works with one location so I don't have to change anything.
• One location makes for a cleaner data entry page. Multiple locations currently requires one form for each possible location as there is nothing in the location module UI for adding another form.
• Works well with views as there is a one to one relationship between location and node.
• My directory is divided by community in the URL. Multiple locations could span communities. Which community do I put the node in? Not an issue with taxonomy as multiple tags work.
• Multi location would look nicer on display of a single node as you'd have one node with all the locations listed along the map and markers on the map for them.
• Multi location is nicer for someone who has a chain where they have 20 identical businesess and they'd need 20 nodes.
• But 95% of the entries in my directory would be businesses with one or at most 3 locations. And more than likely multiple locations would be in separate communities.

If you can't tell by the weighting of my thoughts, I'm leaning towards one location one node. But I'd like to hear other thoughts before I commit to this as it will be difficult to change later. Is there anything I'm over looking that would make multi locations per node a better idea?

One other thing I was thinking is, if I go with the one location model, is adding a node reference field so other locations can be linked. I could possibly take that a step further and show all the locations for all the nodes on each node's map.

Thoughts?
