Reply to Intuition and GUWonder -- I tried to do a dummy booking for many dates from mid-April 2017 through mid-April 2018, and the Choice system always gave me "Sold Out."
The staff member who gave me the information about the management change said that probably the executive lounge would close, but she didn't say anything about re-furbishing the hotel or closing it for renovation. They would not have it closed a year, in any case. The rooms I have stayed in (11th and 12th floors) are very nice, and don't need re-furbishing, in my mind.
As for rates: the rack rate right now for HH members is just over 200 USD which, for Denmark, is pretty good, I think. I suppose this will rise with Choice?
