Admired Much. Slept Little.
My husband and I just returned from a night's stay at the Radisson Blu Hotel. We were in town for a concert that evening and were quite tired and in desperate need of a quick nap when we checked into our room. Catching any sleep was an impossibility. Maybe it was the fact that our room was located in a small alcove. Maybe it was because we were near an elevator, or perhaps it was the ice machine outside our door or housekeeping station next to us. Regardless, I think we had the noisiest location in the hotel. We heard every sound as though it were coming from inside our room. Normally when staying in a room like this I'm able to make things work by using the fan as white noise. Having the fan on high didn't help the problem at all. 
Coming back from our concert around 11 PM, the noise wasn't any better. The last time I looked at the clock it was near 2 AM. 
I made mention of the noise during checkout and the only suggestion was to request a room away from the ice machine when making future reservations. This is a very good tip for those who are considering a stay at this hotel - something I wish I knew beforehand. It was our only true disappointment. The room itself was stunning, cutting edge and lovely to be in, but the eye candy wears off easily if you cannot rest (which is the purpose of staying in a hotel in the first place.)
As for parking, there is a garage adjacent to the hotel, which is what we used. It is less expensive than valet, but there are no in/out privileges, so if you intend to use your car at all, go with the valet service. You'll come out ahead.
