I spent an eternity on this one, because I had to remove/move about 60 tourists from both photos - the only untouched people is the couple nearest to the centre of the photo.
It wasn't so much that I didn't want to see tons of people, but when they move from one photo to the next, it ruins the 3D effect, so they had to go!

It isn't perfect now, but good enough to be enjoyed :-)
