I am looking to booking a couple nights at a property to extend an already existing award stay. Right now, the only available rooms are "Club" rooms, i.e., more expensive than I really want to ideally pay. Also considering that I don't need a club room since (as a Diamond) I should get upgraded to one. I suppose there's a chance that some regular rooms at lower rates will become available between now and my stay mid-March. So my question is: - should I book a refundable rate now (total $100 more than the prepaid rate) and hope for cheaper room to become available? - lock in the non-refundable room and write it off as a lesson learned (should've booked rooms last weekend) How close to arrival to Hyatt properties typically pull the prepaid non-refundable rates?
