I am going to Italy in September, and am wondering what kind of bag I will be allowed to carry into most museums. I don't usually like to check my bags (except in cases where Rick says you can skip the queue!) On previous trips, I have used a bag that looked like a small purse or a small backpack made to hold an SLR camera and lens. I recently bought the Civita daypack and am contemplating buying another point-and-shoot camera instead of bringing my big SLR.
Does anyone have any suggestion for what size or kind of bag I can get away with carrying with me through most museums?
