We have a 3 night stay in July. I booked a standard room and upgraded to the Koestler Suite using a SUA. A Sherlock Suite is available for my stay. It doesn't appear that I can upgrade to it with points but the hotel offered £150/night to upgrade from a Koestler Suite to Sherlock Suite. I know that "it depends" but for those who have stayed in both rooms, would you upgrade for £150/night and why would you do so or not do so? Thanks in advance for any insight.
