Priscilla and Betty,

I think the silver lining in this cloud is that you could use that week to explore the marvelous country that Italy is. Rome is my favorite destination in Italy but anywhere you go in Italy is magical. Tuscany is very special. I don't know if you enjoy traveling by train but the Eurostar service from Roma to Florence( 1 1/2 hr.) and from there into Venice( 2 3/4 hrs.) is very fast and comfortable. You could base yourself in Florence and do day trips from there and you wouldn't even need a driver.
