My March trip report is finally finished. The Venice portion begins at http://mightymac.org/europe12/12europe08.htm
We stayed four nights at the Hotel Campiello, which is a small hotel located on a quiet alleyway located two bridges east of Piazza San Marco and about 100 feet from the San Zaccaria vaporetto stop. We were far enough from Sam Marco that we didn't have a problem with crowds, but close enough that I went there multiple times during our trip
The long trip report begins at http://mightymac.org/europe12/12europe01.htm. We spent only one day in Madrid and one evening in Paris, with most of the trip in northern Italy. This was the first time that either of us had been to Italy or Spain.
