The Hilton Flash sale ends at midnight tonight for stays between 11 March and 3 July 2016.
There are some decent offers – I got a third off an upcoming stay at the Hilton Copenhagen Airport for example.
Rates are not changeable or refundable, and do apply over Easter.
So if you know you need to stay in Europe by early July, get booking.
Also you can get 12.6% back via TopCashBack.co.uk web site.
