I'd like to stay in either of the Union Square zones, the Wharf area or Cathedral Hill (which I don't think has a 4*. I'm not super familiar with San Francisco but I do know that the Public transportation is extensive so as long as there is an easy route to Golden Gate Park, we're cool with staying a few miles away (maybe 2-4 miles away from the park). Last time I was there I bought a hotel from Expedia for $110/night (Argent-Downtown). I couldn't find a deal like that on Expedia today so I thought I'd Priceline it. I'm cool with a budget of anything lower than $110 a night but of course, I'd like to get the best bang for my buck. So, if you have a feeling I can get a 4* hotel at USE for $65 but it will be $90 anywhere else, that's what type of info I'm looking for. I'm not in a giant hurry because I have 4 months before we depart but I thought I'd start researching now.
