You will get a little booklet about 45 days out from your tour start date. If you booked through a travel agent it might be a little later. In the little booklet it will give you what to expect day by day. Not in great detail but when and what you will do in Rome, Tuscany, Florence and Venice.
Enjoy! You will meet wonderful people, see awe-inspiring sites and have the time of your life. We did it in Sept 2008 and re-live (mentally) the whole experience often. I can still see Fred and Ken hugging the wild boar in Orvieto!
Adventurers, Andiamo!
Ciao!
Edit: Take the little booklet with you on the trip. The guides are great at telling you what to expect the next day but it's nice to review it in the morning.
