Rural Areas, Multi Language, Shambolic Addressing

I am working with the free version, I know i will want the full version if i can get my head around some issues over addressing. I could buy it and request a refund if it doesn’t work as i need, but seemed to make more sense to ask here first.
In my home U.K., and I am sure it is the same in the U.S., an address is an address. Everyone knows what theirs is, including the postman. Seems obvious. But my website is in Ibiza, and here things just do not work that way. Our addressing is shambolic, and that is one of the main reasons i think the geo directory will be perfect at a user level, I love the functionality and hope I can find workarounds.
1. Default location.
The island is the island, it doesn’t really have a city as such. There is one of 5 small towns, and it is called Ibiza Town. Setting the default location recognised that Ibiza Town location. I then reset it by dragging the pin to the geographical centre of the island. I set the search radius to 1000 – way more than needed to cover the whole island.
2. Multi language addressing.
The official language of the island, and most reliable in using google maps, is Catalan. However the vast majority of businesses, and the majority of people, use Spanish (trad castellano). There is also some use of English placenames in common use.
3. Shambolic addressing.
Compounding the multi-language issue, addressing is far from a fine science here. Many locations simply do not have postal addresses, I know that sounds mad, but they don’t. Many people rely on post office boxes and ‘send to’ addresses.
They long and short of all this is that in creating places (and in future events), what we and i am sure people creating listings would do is enter broad details, i.e. the closest town or village, and then refine the listing dragging the pin.
I have used this approach importing places, but when attempting to drag the pin just get multiple pop ups (actually really annoying, any movement of the pin requires clearing 10 to 20 of them) stating ‘select address in Ibiza City’.
Some of our issues may be unique, but I am sure people are running the directory in rural areas covering perhaps a few small towns instead of one named city?
Also is there any functionality in the various add ons that allow a user to override an address not found and select location with a pin?
Thanks for any help and thoughts.
