Just got back from the Viva Italia

trip 3 weeks ago.
There really is no need or time to have your iPad with you during the day. I kept mine in the room. I took a small journal and pen with me to make notes throughout the day. I also had my laptop with me and felt secure in having it out on the desk in the hotels.
We kept our passports in the hotel safes, but carried copies with us through out the trip.
Having a backpack with you will come in very handy - just make sure it's not too large. Some of the museums and the Vatican will not let you bring a large one in with you. The
ABD one you receive is an allowable size.
On a daily basis, we carried a small amount of Euros, our debit card for the ATM (bancomat) and one credit card. I had my small Sony Cybershot camera and my husband had his small video camera. We also had street maps of the city we were visiting that day and a guide book.
In addition, I always had a Pashima scarf with me just in case we wanted to go into a church. On the Vatican day remember to NOT wear shorts, you knees must be covered in addition to your shoulders.
Rain during the day is highly unlikely, but being Summer, you might want to pack one of those super small umbrellas, not for rain but for shade. It will be hot and you'll be out in the sun a lot.
ABD provides water for you throughout the day, but we also took a full water bottle with us to start the day. That way we always had plenty.
Personally, I didn't want to leave anything on the bus while we went touring. That's just me, several people left "NON-valuable" items behind, but I wouldn't leave anything of value.
If I think of anything else, I'll update
