We had done this in the past. I researched hotels near the airport before going to the AM's site to book. Once booked I called the hotel with the reservation number to make sure it was classified as Park and Fly and find out if there would be any other fees. Always worked out fine but that was years ago.Has anyone ever booked a park and fly hotel at YYZ through AM.....if I could, I'd like to redeem miles. We need 9 days parking. How do you book this? I don't see anything on the AM site.
We now take the train directly to the airport and stay at the Sheraton Gateway, the hotel that is attached to YYZ. There's no need to wait for hotel bus transfers, you walk out the hotel door and your pretty much in the airport. This is one of the AM's hotels.
Last time we stayed there our son and his family stayed as well. They drove and used the Concierge Park and Fly. Their car was picked up at the airport door and when they were ready to pick it up, it was delivered to them directly to the door. Not sure what the cost of that was but DIL said it was reasonable and very convenient.
