Due to the Hurricane Irma threat advertised on National Television, during our stay in Varadero, Cuba. Air Canada Re-Scheduled our return flight 3 days ahead of initially scheduled and paid for. (My Mother, Father, Husband & Myself) Departed Sept. 2, 2017, Scheduled to return Sept. 9th 2017 (However, returned early on Sept. 7, 2017) We were informed of our return flight change by a door knocker (received at 1:15 am Sept. 7, 2017) Not having any contact info to get a hold of someone or time for that matter, we followed instructions to be ready for pick up in the lobby at 7:00am that morning. Note, we never had a meeting with our Air Canada Rep. or the hotel regarding any evacuation or emergency procedures ahead of receiving the notice for a changed departure time. We would like to request reimbursement for the days which were paid for but lost since we were presented with only one option and no alternative other then to return 3 days of scheduled departure.
