A and D end with "or with the", creating the structure "(without the X) or (with the Y)" or "(with none of the X) or (with the Y)". This reinsertion of "with" makes the parallelism include the former "with"/"without" and creates a readability and meaning issue. It makes it look like the vacationers will either travel without trains or they will travel with hotel accomodation. This disagrees with the logic of the sentence. Eliminate A and D.

要看出来是 the restriction和formalities平行
