i would vote for the radison its a 5 star hotel and ive stayed there once but been inside their cheapest room and their top penthouse suite a few times, i stayed in the penthouse suite but at £550 a night your better off with their cheaper rooms, i think they start at around £100, my cousin normally gets a room when there's a big party coming up or when he's out clubbing, the radisson is beautiful, the lifts dont have any buttons on the inside and are all glass, you need to press the button outside then walk in, the staff are friendly, but at about £5 a drink you better take your own bottle of vodka and a case of red bull, you do get what you pay for as they say as its a stunning hotel even their cheapest rooms blew my mind when compared with any normal hotel/B&B, the hilton on the other hand is slighly uglier, a lot older, and their top penthouse suite is a third the size of the one in the radisson no idea how much it is for the night tho
