My family and I had to go to Montreal from Toronto. We took the train. The Queen E is situated on top of the train station. We arrived at 10pm and walked off the train, took the elevator to the lobby and from there to our rooms. Painless. Our return trip left at 6:45a. We woke up at 6a, checked out at 6:25a and were on the train by 6:35a.
The hotel is also connected to the underground city. Connections to two subway lines, commuter trains, shopping etc are all available without having to leave the underground.
The Queen E's rooms are somewhat dated but they are clean, quiet and comfortable. We had two connecting rooms. This provided more room than a suite at a far lower cost.
