WestJet changed our flight to an overnight layover in Toronto also. We did NOT grab our luggage for the night in Toronto so make sure to pack sleep stuff/outfit for the next day in your carryon.
It did make it nice going to the airport the next morning. Didn’t have to check any bags so we went straight to security.
ETA: I will say the WestJet ppl at the Orlando airport had no clue if we would get our luggage or not lol one guy said since it’s an overnight we would get it, the other guy was like no…this is meeting them at home. So, we still went to luggage area and waited around for it. When it was clear we weren’t getting it we double checked at the WestJet luggage counter and she confirmed it would meet us at home. So, avoid our waiting around and just double check before and then since you have to pass through luggage area anyway, they have workers for their airlines there at little desks so you can confirm with them.
