I noticed a Google ad for a double points promotion for Hyatt Centric Ginza. The code is HCGT01 - valid to 30 April.

It says valid on "an Eligible Rate". I assume the standard rate I booked would qualify - but would it be invalidated by my suite upgrade using points? If it is possible, can I call to have the code added to my booking/


How about the cash and points rate? Presumably no chance of getting double points on the cash portion there?
