The attraction to this hotel is the enormous, four-storey high aquarium around which the hotel is built.

It is really quite hard to beat the lobby of the Radisson with that amazing aquarium. It is one of my all time favorite things to wake up to, watching the scuba divers swimming around with the fish in the morning. Brilliant.
