If your flight is cancelled they Ryanair have to provide you with Hotel costs and meals costs if the delay is more than 1 day,we had our flight to Murcia cancelled during the summer by Ryanair due to the strike by French ATC we flew out the next day same time but we stayed in the airport hotel and had a meal out too.I sent in the receipts to Ryanair for 14 of us and got the cheque out after 13 days covering the costs involved.The Ryanair staff were not too up front at Dublin about our rights but we knew what we were due.
