Hi guys this will be my first time touring San Francisco I am thinking about going around November maybe early December. I wanted to know what are some good locations for a provider to take clients hotel wise also some good restaurants and tourist sites. I do plan to do some site seeing on my down time as well. Any suggestions would be greatly appreciated.

For hotels, in general, Union Square is the place to be.  That's tourist hotel central and pretty much all hotel chains and brands have outposts there.  It's also centrally located for all SF tourist activities.  Have a great visit!

Hello! All Hyatt hotels ( Grand or Regency) are good for providers... Good service, restourants and lounge... They have a good location usually. But sometimes the price can be too hight. I think its depend of events in the city.. In this case I used application in my smartphone "Hotel Tonight" - it help me to take a hotels room on sale. But it's good price on the same day usualy, not in advance . I often used it program in NY, SD, Seattle and SF...  
 Hope its help)

thank you

thanks do you know if those hotel require you to use your room key to get into the elevators after a certain time or can anyone just walk up stairs freely?

Use a large hotel chain and most of the large hotel in SF don't require key access, boutique hotels might.  
Large hotels are used to tons of people flow  in/out and frequenting the bars and restaurants inside.  
They might be a tad more expensive then a boutique hotel, but well worth the anonymity.
