Got this in my email, shouldn't be account-linked as codes seems pretty generic. Pretty sure this is only for hotel bookings, and doesn't apply to flights or packages.
Code: NEWYEAR20 - $20 off for $200-$399
Code: NEWYEAR50 - $50 off for $400-$699
Code: NEWYEAR100 - $100 off for $700+
Says it expires midnight 7th Jan, so book away!

Note to keep a keen eye on the discount, as at some price points, a 10% off code gives more discount.
Eg. I'm looking at a hotel for $620 total. 10% off brings it down to $558, whereas if I used the applicable coupon it only brings it down to $570.
