My sister has some special needs. She's in her mid-60's, and, aside from some other health issues that came up this year, she recently had a large hernia operation plus she's a type 1 diabetic. That all sounds awful but, truthfully, she's doing great and determined to do our 13 day trip to Rome we've been planning. She's only allowed to carry the most basic amount of weight - She had plans to carry a very light smallish day backpack (better than a side bag) - but I am worried about churches and museums. She has to have some emergency snacks with her and her blood sugar reader, her phone and wallet (Her husband will carry the rest).
Tell me: yay or absolute nay to a small light daypack?
Thanks very much.
