My family and I came here to see the holiday cactus lights.
I absolutely LOVE Ethel M chocolates, and it's such to see the Factory in a different setting - decked out with tons of Christmas lights.
There were tons of people there, but parking wasn't hard to come by and there were no lines to anything.
The premise of the event is really simple - tons of beautiful lights, Santa for the kids (I believe a photo is $10) and you can still do a self-guided quick tour of the factory (with a free chocolate coin at the end).
We brought our family dog, a lil bichon fraises (who was a bit nervous at first with all the crowds) but he soon got plenty of treatment/attention from tons of people who wanted to pet him!!
Great family event. They also offer the standard hot chocolate from Ethel's Chocolate Lounges here - yummmm.
