We took the train and did not get a sleep car, we also had Tiffany pick us up.
Tiffany service was great, train ride not so great.
Ride down, 28 hours was OK not great. There are 5 of us so I sat with a stranger which was tough. The lines for food were not fun, the dining room car did not have anything the kids would eat. I was a long night in the seats.
The ride home was worse, stuff stolen, 6 hours late, ran out of food wishing we were still in Disney or home already, will never do it again.
