I stayed a Saturday night and the noise from a wedding reception being held at the Radisson was significantly loud until 2.20 in the morning. The band could be clearly heard as in one could sing along with the words of the songs being played from the hotel bedroom and so I was kept awake until it finished at c.2.20. I rang the reception at c. 1.45 about this and was informed that the band would be finished at 2 which it wasn't. Having said that the gentleman I spoke to at reception was very polite, but from a hotel point of view, I don't think it's good enough at a Radisson SAS that one's sleep should be so affected a reception being held at the hotel, I'm thinking here in terms of lay-out of the hotel and the materials used in the reception area which could possibly buffer of reduce the sound.
