It all clicked in to place (thanks to a little help from Pinterest), our table names are cities we've visited as a couple so we've decided to use a vintage map as a table plan.
Just ordered this lovely map from ebay http://www.ebay.co.uk/itm/Vintage-Retro-World-Map-Antique-Poster-Wall-Chart-Home-Decoration-28-x-18-/350983006169?pt=UK_Art_Photographs_RL&hash=item51b837a7d9
Currently swimming in luggage tags so should have more than enough!!
and hoping the end result looks a little like this -
