Absolutely. The studio is open 7 days a week. If you go on a weekday the glassblowers will be blowing glass for Luke’s production line. If you really want to observe a class, go on a Saturday. It’s classes all day and night.
I guess you can. But if I were you, I would have someone with me take a class and I watch, if I really don't want to participate and just watch only. It will be awkward to just go there and watch. Trust me you'll love doing it actually...
The best way to answer this question I believe would be to actually call the studio and ask.
