|Subject: Re: Niagara Wine Region|
Don't know about tour companies; but would simply recommend you rent a car and drive out to Niagara yourself. They have a great website: http://www.winesofontario.org that has maps, and information on all of the wineries. You can plan your own itinerary, and even make reservations for tours, all online; and probably at a fraction of the cost. The drive from Toronto to Niagara takes about 75-90 minutes depending on traffic.
As for the Festival of Lights, it's spectacular, and well worth the trip again. Hotels book up early though....so make your reservations early.
