I am planning a weekend trip to San Francisco. It has been awhile since I have been there, but in the past I have stayed at the Ritz Carlton and the Grand Hyatt. I have enjoyed the Ritz very much, but I hear that the Grand Hyatt has gone downhill and is no longer even deemed a luxury property.

I see that most of the top properties all have similar rates (ranging from $390 to $415) and am quite overwhelmed by the amount of properties available: Four Seasons, Ritz, Mandarin, St Regis, Fairmont, etc.

Which is the best and why? I would be going by myself (30 year old male) and my main interests would be bar hopping, dining, and shopping. I also would love a hotel with a great indoor pool and spa facilities.

Thanks
