It depends on whether there is something like a convention on a time time, prices are always linked to demand, as for being able to decide which hotel it is or not, based on the 4 Trip advisor rating, it is not the Palomar as that is 4.5 TA rating, the Parc 55, Grand Hyatt or Westin Market street all have a TA rating of 4, the lack of a spa icon may lead me away from the Westin, but it just might not be showing, but between the Parc 55 and Grand Hyatt I would be unable to distiguish. Sorry I can be no further help, I am not a local, far from it I am in the UK, I just go to San Francisco quite a bit to watch baseball lol
