Festivals in Italy

As our planning progresses, I thought I'd look at what events might be going on around us that we didn't want to miss.  Here are the festivals we might be able to catch some of:

• June 22 - September 2 - Outdoor Opera in Roman Arena, Verona.  I wanted to find a way to catch some opera there, but assumed because of the ages of the kids that I'd either have to do it without them or do without altogether.  BUT, Verona is an easy side trip from Venice and outdoor venues are great for little kids (and dad's, too) so maybe we'll be able to do this in the week of July 14th.  Wednesday, July 18th, they're showing Don Giovanni.  I think I know where we will be that day...   http://www.arena.it/en-US/arena/schedule-2012.html
• June 23 - Corpus Domini (procession on carpet of flowers), Orvieto.  http://www.italymag.co.uk/italy-featured/events/three-best-infiorate  This is also called the "infiorate".  Orvieto is an easy trip from Rome and we'll be there at this time. 
• June 24 - St. John the Baptist Day, Italy.  I don't know what this means, really - how they celebrate or what it entails, but we'll be there!  
• June 29 - Sts. Peter and Paul Day (fireworks in Rome).  Hey! We'll be in Rome on this day!
• Late June - Early Sept - Outdoor Cinema Season, Florence.   http://blog.firenzelodging.it/cinema/ Sounds great.  
• July  - Aug - Florence Dance Festival, Florence, Verona.  

Hopefully, these will be opportunities to fill out a lot of our super touristy activities with things a little more local and/or low key.
