American Express is running a promotion with Hyatt for a special rate that allows you to book a four night stay for the price of three from December 1st, 2014 through March 31st, 2015. A lot of times these “special rates” are actually marked up significantly from the regular rate, the end result being not much in the way of actual savings. But this rate appears to be tracking the Hyatt Daily Rate, which means that you actually can save up to 25% on your stay.
(EDIT: Unfortunately, the Park Hyatt Tokyo has opted out of this promotion.)
When searching for availability, be sure to use the “Special Offer Code” AX701, as in the following example for February dates at the Andaz Tokyo:
If there is availability for all four nights, the “Amex Buy 3 Get 4″ rate will show up, with the Average Daily Rate being the value of the Hyatt Daily Rate (or Andaz Rate for Andaz hotels) with the last night’s rate fare waved. In this example, it is three nights at 42000 yen and one night at zero yen, for an average rate of 31500 per night.
The only limitation of this rate is the requirement of an American Express credit card for payment. Cancellation policy is the same as the Andaz Rate (or Hyatt Daily Rate at other hotels), for a rate much cheaper than the more restrictive Advance Purchase rate.
As always, it is best to book fully refundable fares and check periodically for better offers. This is a good deal, but we should always be on the lookout for more!
