Getting ready to make a reservation at the Berlin Radisson Blu. I am a Gold due to having the CC Visa. Should I book a regular room at 44,000 points and hope for an upgrade to an executive room or just book the executive room at 66,000 points to guarantee I get the room? I could live with the regular room (I can stay almost anywhere and be happy as long as the room is clean and I have my own bathroom). I have heard that upgrades are better at many of the CC hotels in Europe.
