was around the San Jose area for more than a year without even a tupperware to put my gear in. i just leave it in my camera bag. i do take the stuff out regularly to shoot so that helps keep the mushrooms away. you'd be fine and there'd be plenty to keep you busy shooting. have fun!
I spent 4 to 5 years in San Jose, Sunnyvale and Santa Clara back in 1990s. The weather was always nice. But it could rain (more like heavy drizzle) for days. Anyway, I did not have any dry cabinet then and I faced no problem. However, I did use my gears pretty regularly.
