Can I bring suitcases on the tour bus? Small suitcase, 20 inches

There are no clear regulations, but try to bring as few things as possible, after all, it is not convenient to play

I want to climb the mountain, dear, I have already reached the mountain by the sightseeing car, and I can’t take the suitcase

It can be that you are too tired yourself, can you deposit it down the mountain?
