First ever post so be nice!
Was just e-mailed the link by Swallow hotels. You can stay at any (I think) of their hotels on a Sunday night for £19 (limited number of rooms), from now until March next year.
Great price which includes a full English/Scottish breakfast! You may need to book early as the number of rooms are limited. Not quite sure when the offer ends, however stays can be taken until the end of March.
