Yes you can spend some time doing it. Workshops are about 30-40min long if u choose to do one. Museum can be done in an hour if you don't stop and check everything out. Count another 30min for the gift shop. Ball park low probably 2-3h. Taking ur time and grabbing a bit to eat could add another 2h on top.
We stopped on our way home from a wedding, and we had 3 young boys, so we spent about 4 hours there. We did a tour, saw the glass blowing demonstration, and the miniature glass making and did the whole museum. I wouldn't have stayed any longer with the boys, but had it been just my husband and me we probably would have stayed longer.
It can take as long as you want...even multiple days. We spent a good 8 hours and enjoyed every minute!
