Related: We booked a points stay some time ago for a couple of weeks from now. Prices were high. Now they have quite good cash rates (like EUR 120) for non-refundable bookings. This is a Twin and we have a King. As Diamond, I'm thinking a good bet to just book the cheaper Twin and count on an upgrade (Executive rooms are available).
Sound like a good plan?
Unless the hotel is near capacity for the dates on which you plan on staying, I would consider doing it.
This is a good hotel property at which to stay. I recommend it.
