Radisson Blu Aqua in Chicago is a superb property in a great downtown location, but there are not many other decent Carlson properties in the domestic US to my knowledge?
(Bonus trivia; in Episode 1 of the excellent new Netflix series The Ozarks, someone gets murdered by being thrown from one of the very high apartment balconies in this building!)
Luckily my stamping ground in Scandinavia, where Radisson maintains very strong presence in almost every significant city.
