Next weekend my husband and I are flying with friends to visit Niagara Falls. We're flying into Buffalo and renting a car. Our return flight leaves Buffalo airport 11:00 am on Monday, July 24th. What time do you think we need to leave our hotel on the Canadian side to get to the airport. Please take into consideration the time it takes to drive from Niagara Falls to Buffalo, and the time it will take to get through customs. I don't know if this speeds up the process, but we all have passports. I'm thinking we need to leave the hotel about 7:00 am, but maybe someone here can provide better insight into the process.
