If panic, anxiety of being in a foreign place make you to write so interesting and well, maybe we should gather money and send you again on a trip :-)

I enjoy a lot reading this thread (too bad I can't be sure it would be saved on my profile and I might lose a day or two from your trip)! It makes me aware of things that I wouldn't even think of.

Three friends wrote and sent me a lot of photos when they visited Las Vegas but no one like you! I noticed that there are a lot of things to visit there, other than Casino. You'll get familiar with the European architecture too. Find someone to walk on those streets. For me there is no fun in walking alone without someone to comment about what we see.
And do complain! I like a lot how are you doing it! And we all usually feel better after! :-)
