well we have not booked yet, there booking rate for the period of our stay is low, so holding out for some specials closer to the date.
last time we got a 2 nights for price of 1, and a free bottle of wine and a room upgrade
But the plan is The Westin Denaru
a few site like booking.com tell you when more than 50% of rooms for a period of time are taken.
So I use that to gauge if there will be discounts or not.
