From Pearson directly it probably a bus. You’d probably have better options taking the Up Express from Pearson down to Union Station, then taking the Go from Union to Niagara Falls. Go only has a couple trips a day that run all the way to Niagara though, but you might be able to do a Via train from Union instead. Then just Uber the last leg from there to your hotel.
Those are pretty far away from one another, and it could be tricky to get to if you have a lot of luggage.
You might want to use a tour bus if you do have a lot of luggage. If not, you could look into Go Transit. Not sure where you'd get on, but I think they've got trains that go directly there.
Thanks but where in Niagara will that drop us off? Does it stop at certain hotels or a central station?
It might take you direct to your hotel. You should confirm by emailing the company.
I believe you can tell Niagara Airbus where to drop you off when you schedule your ride with them. My sister's used them a few times to get from her house in St. Catharines to Person or Buffalo and they picked her up at her place.
Now I have their damn jingle stick in my head. Just 1990s Niagara things...
