aynne, I highly suggest that you be as open as possible with your project, and talk to lots of people about your idea. Many of the people that come to DevHouse are more than happy to offer advice and give tips on how to get stuff working, even if they are really busy with other things. Be sure to bring some of your own projects too, I think you'll have a great time!
If you are coming to SHDH from the South Bay, I suggest parking at the San Bruno BART station and taking BART to the Civic Center station. Sandbox Suites is only a few blocks from the Civic Center BART station!
