I am in the hotel industry in an NHL city and can tell you that teams typically stay near the area they will be playing in, but it is up to the individual teams to decide which hotel to use. Thus, you cannot say with any certainty where a team will stay in an particular city.
Varies, once the new Westin near Crabtree Valley Mall is complete visiting teams will likely stay there.
Most teams stay at the Fairmont Royal York on Front Street due to the quality of the hotel and its proximity to the ACC. I met Kevin Durant there earlier this year.
NFL teams don't typically visit Toronto as there are no NFL teams there. When in nearby Buffalo however they stay at either the Hyatt or Adam's Mark.
