Warwick revisted, not as good
I stayed at the Warwick with my wife and daughter this past summer and it was great! Maybe it was the warm weather, but when returning for the winter it was not so good. My wife had her company book their group there because of our previous experience.
The room was like a sauna, I finally got the heat controled by turning it off, and having the window cracked open (fun to do in a snow storm). I had hoped they would put me in a room comparable to what I had before, but instead it was smaller(even though I asked for what we had before). 
The worst though was room service. I ordered wine with our meal, and when the room service person attempted to open the bottle he destroyed the cork(sending it all over the floor) and said he would be right back with another bottle. 20 mins later with my meal nearly done still no sign. Long story short, I get the bottle about an hour later, they said they would take care of my bill(free wine, should have comped the meal). The issue, so they say, was that they could not find another bottle, I say then just upgrade to the next priced bottle, not have me wait over an hour! 
So room service so bad I would never try it there again, service that stunk because management should no how to deal with a problem, especially when, as in our case, there were 3 rooms booked for 2 nights through us in total. Location, is still great, rooms are still big, but the issue with the service means we will probably not stay a third time.
