Earlier you book - the more available...........heads up booking starts saturday.
Thanks to Martin on MSE - Notes: This Sat 26 Sept at 00.01am, Holiday Inn is launching a £29 & £35 UK Christmas room sale. Holiday Inn Express rooms (usually £40-£60) will be £29 and Holiday Inn rooms (usually £50-£80) £35. There are also Crowne Plaza rooms for £49 (normally c. £70). Stays must be between 17 Dec - 31 Jan.
There will be 10,000s of cheap rooms up for grabs, and the deal will be visable on the homepages of Holidayinn, Crowneplaza, and Holidayinnexpress. There is no limit to the number of nights you can stay. A few London hotels will add taxes on top of the £29 / £35, but the press office confirmed that amount you will pay will be clearly displayed.
