I think definitely. The amount of money they bring in through tourism way outstrips what they cost us. 62p is not even 1 1/2p a week! Plus the Royals can be very useful in diplomatic terms. Look at Charles and Camilla's trip to Saudi Arabia earlier this year - hugely successful, and they were treated with reverence wherever they went. Several Middle Eastern countries that would happily bomb a Prime Minister or President will respect royalty.
