imo i'd post in both the san francisco boards and the gold coast ca boards.  gold coast is a bit south of san jose but would still be relevant.

can't help you with where to stay; sj has changed since i was there...

Unless there is an overpowering reason why you are staying in San Jose, I'd think seriously about driving 50 minutes (depending on traffic) south, or taking Cal Train, and spending at least day in San Francisco, probably in the Union Square area.I think you'd do some business, and if you have spare time it is a much, much better place to sight-see.  

Hope you have a great trip!

Your ad says you're visiting San Jose Feb 6-7.  Are you in town for the Super Bowl?

I don't know what hotel availability or rates are like this weekend.  I had assumed that everything would be booked up and rates would be sky high.

But then there's this article that just came out in the San Jose Mercury news.

http://www.mercurynews.com/sports/ci_29470863/despite-hype-super-bowl-50-is-mixed-bag

so it sounds like rooms are available and not too pricey.  San Jose isn't really my area but I've seen people stay in Santa Clara.  However, the Super Bowl is in Santa Clara.  People also stay in Mountain View and Sunnyvale, but these are also close to Santa Clara.  There are some decent hotels in San Jose by the convention center and airport.  The article also mentions Santana Row which is very nice.  

Like Will said, you may want to consider heading north towards San Francisco.  There are a lot of hotels near the San Francisco airport, convenient for both people in San Jose and San Francisco.  Look for hotels in Burlingame, Millbrae and San Mateo.  If you head into San Francisco, there are many hotels in the Financial District/Union Square area, this is the heart of the city with lots to do during off hours.

Palo Alto and Redwood Shores have some nice hotels as well

San Jose

It kind of depends upon what you really want.   There's a mix of cheap-shabby and decent hotels near SJ Airport (SJC) - most are convenient for customers wrt parking.  Downtown is classier.  Santa Clara is nearby and has some more upscale accommodations near Great America / Levi's Stadium as well as cheaper and sometimes shabbier a bit distant from that.  I'd tend to recommend checking out hotel reviews for the ones near SJ Airport.

Just g'gle "SJC Airport Hotels" and check reviews.  And WELCOME to San Jose
