DON'T SIT ON THE SPANISH STEPS...
...and a lot of other sites in Rome!
That's right! No sitting and no eating. But Rome has done this before.
It depends on your point of view.
Do you want the steps so crowded that it's almost impossible to walk
up or down? (You can take an elevator, you know.)
Do you want to walk through someone else's lunch remains? I don't think so.
You'll just have to get used to standing for those pictures you love so much.
By the way, there's a hefty fine of up to Euro 400 that comes to approximately $440 at todays rate...so don't be a hero.
There are some other well known sites that will probably be off-limits to the tourists. Don't try jumping into the Fountain of Trevi. Except for Anita Ekberg in the movie "La Dolce Vita" and some other hundreds of people when Italy won the World Cup in 2006, the polizia turned their heads. Do you recognize that guy with the flag wrapped around his neck?
I wonder what the rules will be if Rome gets hit with another snowfall as they did this past winter? I guess you can slide down.
