We went to California for 2 weeks (started in San Fran, drove down the coast and ended up at
Disneyland) and it was the best trip we've ever had! There is plenty to do but I'm not sure how the weather is in Feb...we were there in July and it was cool. We rented bikes and rode across the Golden Gate bridge, took a trip over to Alcatraz, rode the cable cars, walked down to the pier to see the fisherman and the sea lions..there's more to do but we were only there 2 days! As far as hotels, right in the city it's pretty pricey with most hotels charging $25-30/night parking as well but again, we were there in July which might be higher season. We used Hotwire and got a really good rate to stay in Fisherman's Wharf which is a very good location for all of the activities I mentioned. I'm not sure about suite type hotels right in the city but if you go on trip advisor it gives a good review of accommodations in the different areas. Have a great trip!
