Coming into town with three friends (early thirties) who have never been to San Fran. Looking for advice as I decide between the Sheraton Fish Wharf and the New Westin Market. Would rather cab it to the touristy things we want to do-Fish Wharf, Alcatraz, Chinatown, baseball game etc. and be closer to the nightlife/good restaurants when chosing a hotel location. Are either of these SPG props close to the bars / clubs /restaurants etc? We don't mind walking a bit either. Thanks.
