Admittedly not sure, but I seem to recall hearing that Obama costs the yanks loads more than Liz costs the Brits.....I am open to correction on this.    Royalty pads not in the top 50 ?. Seems a limited way of assessing royalty tourist income. I,m pretty sure all those gift shops in London don't stock all that tat out of loyalty !    Not really mega royalty, especially all the hangers on, but I,ll say it too....God save the queen .
