It seems like under 100 a night would be a bit rough to find in SF. Even if you do stay in SF you'll probably need to drive around to get around to different places as downtown, union square, fishermans warf, pier 39 are far apart and would be a long walk with kids and a taxi service would cost 10-15 each way. Most hotels in SF are a valet only properties. I know the Marriott in SF is $55 per night! I would recommend staying in Walnut Creek which is a city about 25 miles from SF and only a 30-45 minute drive depending on the traffic. I work at the rennaisance clubsport valet an are usual nightly room rate is around $100 on weekends. We get mostly business people during the week who are in the east bay or SF for business. With Priceline you might be able to get 50-60 a night. Its great for kids because we have 1 large lap and recreation and one medium kid pool both about 5 feet deep and a baby pool and a hot tub. Kids have a blast out there, I did to the summer I spent life guarding out there. It's real child friendly. There is also 2 full length basketball courses and fitness classes from yoga to tie bo to cycle going all day long. It is all included in your stay with no extra resort fee! They have poolside cabana, a resteraunt to eat, and a deli. The hotel is real small with only 175 rooms so you recieve top notch service as were consistently ranked top two hotels on are customer review score within the rennaisance brand. Valet is $19 a night and on weekends there is free self parking off property at the garage next door. It's only 25 miles to the city and it will cost you only $5 or $6 dollars to cross the bay bridge.and $20 to park for the day and 10 bucks on gas. Best deal if you ask me.
