There are no timeshares on Andros Islands. Andros Island's claim to fame is their legendary bonefishing waters, so there are numerous bonefishing lodges. We spent a few days there last October - can't say I saw a "city" to speak of, but then again, we didn't go exploring - just fishing. The lodge wasn't luxurious, just a place to sleep. The people, however, were extremely friendly and helpful.
