Sounds like a good solution, just wondering in case I take a medium size - will I have a problem rolling it outside of Tokyo, as I have been told that Onsens might be located in rural areas, that require a 1.5 KM walk from the train\bus station, and I was wondering how do you roll a trolley there (any size for the matter of fact) in case that there is no asphalt there (could it be that there is no asphalt there?!)
