Your questions have been addressed by others. I might add it is best to go as early in the morning as possible. Because of the altitude (11,333 ft.) you may only feel like staying 3 or 4 hours. By mid afternoon it is good to get a train down the mountain because the cars fill up and are very crowded. Be sure to check the weather before going to the Jungfrau. You don't want to be there on an overcast, foggy day.
