About how long does it take to walk through the whole Glass Pavillion roughly? Trying to plan my day

I think that depends on you. If your a focused reader you can spend as little or as long as you would like. We were only there 30 minutes. We saved more for another day.

I'd say 45 to an hour for the glass only for the Pavillion unless you look at every single piece. It has 5 rooms. And the pieces are beautiful.. if you can catch the glass blowing demonstration that lasts about an hour. The museum itself is a different story 😃

2 hours tops, also saw glass blowing demo

An hour to look at the glass pieces.
