Hi bro, ok so it is called Safeway here is the website http://www.safewaytours.net/casino-tours/ SORRY EVERYONE IT IS NOT AN AD, JUST HELPING SOME PPL GET TO NIAGARA
They go tO Niagara every hour. The only disadvantage - you cannot have anything with you, not even a small bag, what i did was I took my husband's passport and my passport and our COPRs and put them in a pocket in my jacket. If you have a bag or something they will not let you on the bus.
You don't have to book anything you just show up at Yonge and College (Holiday Inn Hotel is where they stop and where their office is) and once the bus stops you will see lots of gamblers get on it. There will be a stewardess or whatever they call her, conductor maybe, just tell her you are going to Casino and you would like to purchase a card, she will let you on the bus and while the bus is on its way to Niagara she will collect money from you ($35). Once you arrive she will walk you to the casino reception and they will print a card for you. After that you can leave the casino, nobody cares what you do after but MAKE SURE YOU PLAY AT LEAST 1 GAME BEFORE YOU LEAVE, they will fine you if your card is not activated. The fine is $70, but just spend 5 bucks and play some sloth machines whatever. After that you can go Niagara as often as you want for $7 per round trip.
Very cool option indeed, we go to Niagara by those buses all the time. All of my friends do as well.
