Check out youtube for videos. There's a couple people who post videos of what's currently available, so you can get an idea of whether or not you want to take the time/effort to get there. The Vineland one is bigger. They open at 10, and there's always a line to get in, as well as a long line to check out. They are super popular and crowded.
We will be taking an Uber to the Vineland location next trip. Can't wait!
