I agree with Karen2 - even "good" shuttle service can take a while due to one-way streets, traffic, etc. Plus who wants a shuttle if you want to go back to your room to freshen up before dinner - better be a late reservation!

As a San Francisco resident, I've never had occasion to sample the rooms/service at any of the hotels, of course. Well, maybe not "of course" - back in the sleazy 70's, I had a friend who had "experienced" virtually every hotel in town!
