SF Nightlife: Hotels in SF after a night out? $100 or less.?

So, we're planning on going out to SF for a night. The usual drinking and eating and dancing. Usually, we drive home which isn't far. However, it'd be nice if ALL my friends could relax and not have to worry about driving back a bunch of drunkards. We are planning on going around North Beach, bar hopping. Maybe Geary/Post if we're up to it. So my questions is: which hotel would you recommend? I'm looking for something cheap. Hostel style is fine. We just need a place to crash for the night. Oh! We need parking spot too. I've checked yelp and google reviews, but I thought I'de give you guys a try.

Also, I would really appreciate if you could recommend any bars in the before mentioned places that is in Frisco without cover charge. I repeat: NO cover charge on a Saturday night.

THANK YOU!!
