I did it in January! It's a reservation meant for two people. My friend couldn't make it, so I did it by myself which was fine. It was very well organized and a lot of fun! The instructor guides you though everything so it's really easy to do. The cast members were all very welcoming and friendly. You are invited to have a coffee, latte, tea, etc. before the class started and then again at breaktime. They display everyone's cakes in the display case and take lots of pictures if you would like. Like a pp said, they can hold your cake for you until you are ready to leave Disney Springs. The cake is an entremet cake, so it must be refrigerated. It did fit into our resort refrigerator.
I didn't love all the components of the cake personally, but the cake itself, and the chocolate mousse were delicious.
I would say it's a great experience, and I fully enjoyed it and I'm glad I did it because it was on my bucket list forever. But I would also say it's pretty pricey for what it is, and it is a one time experience.
