Wow... thanks for all the good advice! This is great information and more than I had expected.

I am planning to go on August 17-19, so it sounds like they will really be shut! Now, I need to see whether I should go or not? In addition to the sightseeing, I was hoping to do some shopping and get some Italian brand clothes that are suppose to be cheaper in Italy than the States, but that plan may not work this time!
