It can take quite a while! How willing are you to cheat and use Google maps and an aerial view of the maze? Many people wander around for an hour or so and then resort to Google. They do have photo ops along the way too. They are numbered to help you know you are headed the right way. Fun evening!
There are several options. Trying without any help or reference can take a long time. If you get the map they provide, as long as you make sure you know which way on the map is north, orient yourself so you know where then entrance and exit is and follow the map very closely, you can make it in about 30 min to an hour. If you use the app they suggest you use then you can probably get through in as little as 15 minutes
