Lovely pictures! Sounds like you had a great time.
Oh, go back to Venice, but not with a tour. I stopped there for 24 hours once, more as a "I really ought to see this place, but I'm not expecting much" and I fell in love. I have a wee bit of a crowd issue, so I made a point of going to the big touristy things really early (ok, sort of early). I think I did the Basillica at 9 am - no line up. By the time I toured the rest of the square it was totally packed. For the rest of the day, I just wandered around the city. If something looked too crowded, I just headed the other direction. Its a great way to see things.
I also had the most terrible and amazing thing happen to me via Venice. I left my journal at a cafe, but didn't realise it until I was on the train for a couple of hours. I was pretty heart-broken. A month after I got home, I got a package in the mail (I thought it was a b-day present from my sister, but couldn't figure out why she was in Austria - not out of the realm of possiblity, but unusual). I opened up the package and there was my journal

. I was so happy. I always put my address in my journals, just in case, and some nice stranger found it and mailed it to me.
