Advice on route

Hi!

Need advice on which route option is better.

Am travelling from NYC to Toronto in mid sep and want to visit Niagara Falls n NOTL.

I don’t drive, so everything has to be public transport.

Will have 1 big check in luggage kind, 1 backpack.

Option 1:
Book a day tour to Niagara Falls, say goodbye to them, walk over to Canada side, deposit stuff in locker, do the boat activities etc.

After which, is it easy to get to NOTL with my luggage and all? Not sure how I’m gonna tour a bit of the wineries.

Then bus/train to Toronto in evening.

Option 2:
Overnight bus to Toronto, check in, explore Toronto, so I don’t waste a day.

Next day book a day tour from Toronto to NF and NOTL

Option 3:
Fly to Toronto. Check in.

Next day book day tour from Toronto to NF and NOTL

2 and 3 are more straightforward I guess cause i don’t have to be lugging luggage and figuring out transport.

But read many reviews against flixbus.

1 is good in that I visit NF on the way to Toronto, so I can use the next day to explore Toronto.

Would appreciate any suggestions, thanks!
