Commentary on this starting point: this may be a favourable case as the cache is centred on an area with lots of attractions, and the area outside the cache has fewer attractions; the cache may, however, be smaller as Plymouth is on the sea, so part of the cache area covers the sea -- which has no tourist attractions.
