So I cashed in my united miles for a family trip to Cancun this April. the only flight I could get for my wife and 5 and 3 year old girls takes off from Ohare at 9:30pm, lands in toronto at 11:30PM, then connects to an Air Canada flight to Cancun at 8:30 the next morning. We figure it's not worth getting a hotel room, since it will take a while to get through customs that night and and we need to be going through security the next morning no later than 6am. I contacted the airport and they won't let the the family stay on the gate side. At this point, they are probably going to take a couple of sleeping bags and find a quiet corner of the terminal to camp out in until security reopens at 5am. I even thought about taking a little kids' tent since the more sleep the kids get, the better. Does anyone know this airport well? Are they accomodating and tolerant, or will this be a big hassle? What does everyone think?
