This is a great deal, giving you £25 voucher for food and drink to spend at the hotel..
All you need to do is to spend £50 during your stay, so if you spend £25 per night on dinner for two nights, the third night's dinner will be free. And the good this is you don't necessarily have to stay at the hotel.
Parking can also be included, so useful if you are wanting to leave your car at the airport hotel during a short trip to Europe.
Great deal, great food.
