OK it wasn't for a Skiathos holiday but I've been informed that Ryanair have finally released the money to the agent I used to book a sneaky week in Tuscany in June this year (which never happened obviously). Should have the flight money back in my account shortly. It wasn't a lot but it will keep me in beer next Skiathos trip next year. The company also offered me a bonus if I took a voucher from them for the hotel booking part of the package rather than a cash refund so I used them again to book the hotel in Skiathos next year, effectively giving me £25 off the booking. I was thinking of using them again anyway so the extra bonus was nice, they offer some of the best value packages in any case. Won't be using Ryanair again any time soon if I can avoid it.
