Hey everyone, I just landed in Montreal for the first time and I'm trying to figure out how to get to my hotel near Place des Arts. I saw there's a bus called the 747, but is that reliable? I heard about the train too, but it doesn't seem to go directly to the airport. Uber is tempting but I'm on a budget. Honestly, I'm a bit overwhelmed with the options and don't want to mess up my first day. Any tips from locals or seasoned travelers? Also, is it easy to buy a ticket at the airport or should I get a pass beforehand? Thanks in advance!
