I need help to settle an argument.

A friend of mine is going to Italy and will be visiting small towns. That means his bag will have to go from the train station to his hotels on rough pavement and cobblestones. (No cabs.)

He only takes carry on size luggage. He thinks he'll be fine with his new four wheel spinner. I say he should stick with his rolling bag (2 wheels) for this type of trip as the spinner wheels may not be able to handle it.

Anyone have experience with carry on size spinners in this type of situation?

Thanks.
