Day 15: We are really sad to be going home. Have hardly thought about work and have had a totally amazing time.

Just manage to muster enough enthusiasm to take a blip looking back at Vegas from the airport terminal before we board the plane for the hideous red-eye flight back to chilly London.

I have of course taken many hundreds of photos on this trip and it is hard selecting one for each day when there is so much good stuff. I'll post a wider selection to my Flickr account over the next few days.
